libperf: Add perf_mmap struct
Add the perf_mmap struct to libperf.
The definition is added into:
include/internal/mmap.h
which is not to be included by users, but shared within perf and
libperf.
Committer notes:
Remove unnecessary includes from tools/perf/lib/include/internal/mmap.h,
those will be readded as they become necessary, later in the series.
