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.
