tools headers: Syncronize mman.h ABI header

To add support for the MAP_SYNC flag introduced in:

  b6fb293f2497 ("mm: Define MAP_SYNC and VM_SYNC flags")

Update tools/perf/trace/beauty/mmap.c to support that flag.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman.h' differs from latest version at 'include/uapi/asm-generic/mman.h'
