llvm-cov: Another fix to llvm-cov test.

Copy all test files to temporary directory, not just test.* files. Tests
didn't fail because the missing files occurred in XFAILS.

Return true on success in cl::ExpandResponseFiles

This fixes a logic bug pointed out by Juraj Ivancic.

No behavior change because none of the in-tree clients of
cl::ExpandResponseFiles check the return value.  In this case, the
@prefixed arguments are left in the command line.  Downstream command
line processing has the opportunity to emit errors about it, so this
isn't that bad.
