perf syscalltbl: Support glob matching on syscall names
With two new methods, one to find the first match, returning its syscall id and its index in whatever internal database it keeps the syscall into, then one to find the next match, if any. Implemented only on arches where we actually read the syscall table from the kernel sources, i.e. x86-64 for now, all the others use the libaudit method for which this returns -1, i.e. just stubs were added, with the actual implementation using whatever libaudit functions for matching that may be available.
