perf tools: Add possibility to specify mmap size
Adding possibility to specify mmap size via -m/--mmap-pages
by appending unit size character (B/K/M/G) to the
number, like:
$ perf record -m 8K ls
$ perf record -m 2M ls
The size is rounded up appropriately to follow perf
mmap restrictions.
If no unit is specified the number provides pages as
of now, like:
$ perf record -m 8 ls
