tools, vm: new option to specify kpageflags file

page-types currently hardcodes /proc/kpageflags as the file to parse.
This works when using the tool to examine the state of pageflags on the
same system, but does not allow storing a snapshot of pageflags at a
given time to debug issues nor on a different system.

This allows the user to specify a saved version of kpageflags with a new
page-types -F option.
