Fix common.sh Weirdness

[calccrypto]

tests/CMakeLists.txt was calling configure_file without a copy method, and it was copying common.sh weirdly
also fixed a few other issues that were prevented by this issue/missed in the previous shellcheck commit

updated test_xdd_reopen.sh

• grep for the words, not just the strings
• ignoring syscall count mismatches for now (see Tests are probabilistic #19)

@calccrypto can you update this to also have a commit where we just skip the test_xdd_reopen test case and open an issue? That is something we need to figure out, but that can be done in another PR.

@calccrypto I just realized you already had the reopen test_finalize passing -1 on failure. I didn't notice that before. We probably can just drop your latest commit for the CMake variable and just merge the your initial commit in. Sorry for now noticing this before now.
