  [SystemZ][z/OS]: fix lit tmp_dir to use - instead of _

Latest upstream change in https://reviews.llvm.org/D117179 causes lit regressions on z/OS, when TMPDIR is exported and contains _, ld linker fails, it doesnt recognize _ specified in SYSLIN. this seems a limitation on z/OS. we need to fix lit.
