Removed get_pageshift(). Every one can affort a * instead of a >>, no need

* glibtop_server.c:
	* glibtop_server.h:
	* procmem.c: (glibtop_get_proc_mem_s):
	* procsegment.c: (glibtop_get_proc_segment_s): Removed get_pageshift().
	Every one can affort a * instead of a >>, no need for this kind of
	non-reentrant optimization. Saved 144B (obviously perfect cleanup ;)
