* Fix failure installing yarn 1.22.22

In #1516 there were reported build failures:

```

This is because older versions of the yarn package have a top level directory that looks like this:

```
yarn-v1.22.19/
```

But yarn 1.22.22 has a directory named "package" instead:

```
package/
```

To work around this naming issue we can use `--strip 1` tar flag to remove the top level directory. From gnutar manfiles https://www.gnu.org/software/tar/manual/tar.html:

```
‘--strip-components=number’
Strip given number of leading components from file names before extraction.

For example, suppose you have archived whole ‘/usr’ hierarchy to a tar archive named ‘usr.tar’. Among other files, this archive contains ‘usr/include/stdlib.h’, which you wish to extract to the current working directory. To do so, you type:

$ tar -xf usr.tar --strip=2 usr/include/stdlib.h
The option ‘--strip=2’ instructs tar to strip the two leading components (‘usr/’ and ‘include/’) off the file name.

If you add the ‘--verbose’ (‘-v’) option to the invocation above, you will note that the verbose listing still contains the full file name, with the two removed components still in place. This can be inconvenient, so tar provides a special option for altering this behavior:
```

* Default to strip 0 instead of true

From the feedback:

> Minor - maybe the default for strip_components should be 0 instead of false? From this signature, I would expect that if I want it to strip components I would pass true instead of false but that would produce an invalid command.
