perf header: Add is_perf_magic() func
With this function, other modules can basically check whether a file is
a legal perf data file by checking its first 8 bytes against all
possible perf magic numbers.
Change the function name from check_perf_magic to more meaningful
is_perf_magic as suggested by acme.
