libperf: Move 'page_size' global variable to libperf
We need the 'page_size' variable in libperf, so move it there.
Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.
Committer notes:
Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.
