[PATCH 58/63] perf beauty mmap: Print mmap's 'offset' arg in hexadecimal

Also to make it match 'strace' output, for regression testing.

Both now produce this option, when 'perf trace' uses a .perfconfig
asking for the strace like output:

mmap(0x7faf66e6a000, 1363968, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x22000) = 0x7faf66e6a000
