80c21797 - [BOLT] Fix tests that were unresolved when using lit's internal shell

[BOLT] Fix tests that were unresolved when using lit's internal shell These two tests were unresolved when using lit's internal shell. In the case of tail-duplication-constant-prop, it was because they were using a echo $? line, and lit's internal echo implementation does not support $? to get the return code. The test was never actually asserting anything about the return code though, so I've removed the echo commands. In the case of permission.test, it was because umask was not supported before #155850, and afterwards not without an argument. The test also was not great at capturing what it was supposed to (leaving open possibilites like the system umask and what Bolt was using happening to match), so I've rewritten the test in the style of llvm/test/tools/llvm-objcopy/ELF/respect-umask.test. This fixes #102693. Reviewers: maksfb, yota9, ayermolo, yozhu, aaupov, rafaelauler, paschalis-mpeis Reviewed By: maksfb Pull Request: https://github.com/llvm/llvm-project/pull/156082
