selftests: vm: refactor run_vmtests.sh to reduce boilerplate
Previously, each test printed out its own header, dealt with its own return code, etc. By just putting this standard stuff in a function, we can delete > 300 lines from the script. This also makes adding future tests easier. And, it gets rid of various inconsistencies that already exist: - Some tests correctly deal with ksft_skip, but others don't. - Some tests just print the executable name, others print arguments, and yet others print some comment in the header. - Most tests print out a header with two separator lines, but not the HMM smoke test or the memfd_secret test, which only print one. - We had a redundant "exit" at the end, with all the boilerplate it's an easy oversight.
