bootstrap: Remove rustc_snapshot_libdir from PATH in one more place

[petrochenkov]

Same as #141657 but in a different part of the build system, with the same goal of addressing #t-infra/bootstrap > Build broken in MSYS2 @ 💬.

It seems to work on windows-{gnu,msvc} and linux-gnu at least.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
