[compiler-rt] Don't exclude ubsan-asan tests on Windows/x86_64 (llvm#137171)

This removes a leftover workaround from
00f3f6e from 2016. Currently the tests
seem to work fine on x86_64 in both MSVC and mingw configurations with
this workaround removed.

(On aarch64, asan isn't functional at all; this workaround used to hide
that issue when running "check-ubsan", but the issue is apparent if
running all tests with "check-compiler-rt" anyway.)
