[compiler-rt] Mark some tests as unsupported on Windows.

PR157951 removed 'REQUIRES: shell' from several tests, which
(among other things) caused them to start running on some
Windows builders -- the 'REQUIRES: shell' prevented that.  Some
of those tests fail on Windows. This PR marks those failing tests
as UNSUPPORTED on Windows.
