Fix using Chromium installed via snapcraft

[flotwig]

• Closes Launch Hanging on Ubuntu when snap version of Chromium is installed #7020

User facing changelog

• Fixed a bug preventing Cypress from launching on systems where Chromium was installed via Snapcraft.

Additional details

• in cypress open, project would never load and spinner would run forever. on cypress run, no output is printed to the console (browser detection runs before anything is printed)
• mysteriously, execa would hang on --version when used with the snap
• switched to using cp instead since execa is only really used for windows benefits and it works fine
• added a 5s timeout to getVersionString since it should never take that long
• still having issue due to snap sandboxing, cannot create browser profile: Launch Hanging on Ubuntu when snap version of Chromium is installed #7020 (comment)
  • instead of writing to the usual appdata dir, write to $HOME/snap/chromium/current/Cypress since that's the only place this chromium can write
  • tested locally, would also like @bkucera to test on his system

PR Review Checklist

If any of the following requirements can't be met, leave a comment in the review selecting 'Request changes', otherwise 'Approve'.

User Experience

• The feature/bugfix is self-documenting from within the product.
• The change provides the end user with a way to fix their problem (no dead ends).

Functionality

• The code works and performs its intended function with the correct logic.
• Performance has been factored in (for example, the code cleans up after itself to not cause memory leaks).
• The code guards against edge cases and invalid input and has tests to cover it.

Maintainability

• The code is readable (too many nested 'if's are a bad sign).
• Names used for variables, methods, etc, clearly describe their function.
• The code is easy to understood and there are relevant comments explaining.
• New algorithms are documented in the code with link(s) to external docs (flowcharts, w3c, chrome, firefox).
• There are comments containing link(s) to the addressed issue (in tests and code).

Quality

• The change does not reimplement code.
• There's not a module from the ecosystem that should be used instead.
• There is no redundant or duplicate code.
• There are no irrelevant comments left in the code.
• Tests are testing the code’s intended functionality in the best way possible.

Internal

• The original issue has been tagged with a release in ZenHub.
