Bug 1757813: Detect "MSYS" unames as `msyshost`s r=firefox-build-system-reviewers,nalexander

MozillaBuild 3.4's kernel name was `MINGW32_NT-6.2`, but the new
MozillaBuild's kernel name looks like `MSYS_NT-10.0-19044`.

Update existing first-party detection code to properly handle the modern
MSYS "kernel name" format.
