further improvements for extraction of MSI and PKG

[hohwille]

As discussed in PR #1002 I want to further improve our doInstall function to avoid quirks in the commandlets:

• with Support for MSI #978 we have added support for MSI extraction. However, msiexec does not only extract the MSI file but also creates a copy of the MSI in the target folder. This is undesired. As I did not find an option for msiexec to prevent this nonsense, we should simply delete the copy after calling msiexec.
• the same way we support MSI now (Support for MSI #978), we should also support pkg packages on macos and automatically extract them rather than doing this manually in our commandlets. Again everything can be found in #978 support for msi and adjustment of aws commandlet #1002 (see my review comments)
• we already do support special cases where an extracted package only contains a single folder that then contains the actual content. If so, we simply take that content and therefore omit the single folder automatically. For e.g. AWS we would need to extend this so it works in a loop so that also a 2nd level single folder can be omitted. However, besides *.app folders we would also need to exclude bin folders to avoid accidental buggy behavior:
  

  ide/scripts/src/main/resources/scripts/functions

  Line 809 in 478794d

  function doReplaceExtractedSkipSingleFolder() {

• at the end we should remove the "workarounds" from the AWS commandlet that are now already handled by our updated functions.

Examples to make the last point clear (the asterisk * marks the folder containing the content that should appear inside the target folder such as software/«tool»):

«package1 root»
└── Amazon
   └── AWSCLIV2 (*)
      ├── _asyncio.pyd
      ├── ...
      ├── aws.exe
      ├── ...
      └── wheel-0.37.0.dist-info

«package2 root» (*)
└── bin
  └── my-tool

«package3 root»
└── Foo (*)
  └── bin
     └── my-tool

«package4 root»
└── Foo (*)
  └── MacOs.app
      └── Content
          ├── bin
          ├── ...
          └── README.txt

The extraction code for pkg from aws command was:

  elif doIsMacOs
  then
    doEcho "Installing AWS for MacOS..."
    sudo installer -pkg "${path_to_package}"/aws-"${version}"-mac.pkg -target /
    if [ "${ERR}" = 0 ]
    then
      xar -C "${AWS_HOME}" -xf "${AWS_HOME}"/aws-"${version_to_install}"-mac.pkg
      tar -C "${AWS_HOME}" -xzvf "${AWS_HOME}"/aws-cli.pkg/Payload
      rm -rf "${AWS_HOME}"/Distribution "${AWS_HOME}"/Resources "${AWS_HOME}"/aws-cli.pkg
      [ ! -h "${AWS_HOME}/aws" ] && ln -s "${AWS_HOME}"/aws-cli/aws "${AWS_HOME}"/aws
      [ ! -h "${AWS_HOME}/aws_completer" ] && ln -s "${AWS_HOME}"/aws-cli/aws_completer "${AWS_HOME}"/aws_completer
      [ -f "${AWS_HOME}"/aws-"${version_to_install}"-mac.pkg ] && rm "${AWS_HOME}"/aws-"${version_to_install}"-mac.pkg
    fi
