cmd/link: ensure cgo cflags do not leak into tvOS test

Running the 'TestBuildForTvOS' test with CGO_CFLAGS set
with certain values would cause the test to fail. all.bash
would fail when CGO_CFLAGS was set to '-mmacosx-version-min=10.10'
because the --macosx-version-min flag is incompatible with tvOS.
The change guards against using an unintended flag in the unit test.

Updates #35459
