tests: check decoding of madvise, mlockall, mremap, and msync syscalls
* tests/mmap.c (main): Change output format from regexp to verbatim. Add tests for madvise, mlockall, mremap, and msync syscalls. * tests/mmap.test: Convert from match_grep to match_diff. Add madvise, mlockall, mremap, and msync syscalls to syscall filter.
