[Bug 2049678] [NEW] Some UI tests could fail under certain build path names

[Zixing Liu]

Public bug reported:

It is known that the rustc build could fail due to version number or
build path containing special characters like `~` or `|`.

The UI test could also fail if you have a very long version number.

The issue is determined to be the UI tests do not account for the cases
where the Rust compiler outputs the quoted path name or writes the path
name to a file containing the error diagnostics to avoid printing a lot
of data to the stdout.
