[ruby/bundler] Skip the mswin-specific specs only on mswin, not mingwHEADmaster

These specs guard limitations specific to the mswin build: nmake has no
make jobserver, the generated Makefile uses MSVC `-libpath:` syntax,
extensionless executables cannot be exec'd, and the raygun-apm fixture
only ships an x64-mswin64 variant. The mingw build passes them, so match
the platform string directly instead of Gem.win_platform?, which is also
true on mingw. The MAX_PATH and cross-drive guards stay on Gem.win_platform?
since those limitations are not specific to mswin.
