llvmPackages.compiler_rt: Fix compiler_rt version tests for git

Without these fixes, the git build currently fails because the tests are
out of date.

One is updated since it was fixed upstream, the other is still needed
for the git build, but testing `version` resulted in a test against the
`unstable-*` string and not the one with the version number in it.
