tools/vm/page-types.c: cleanups
Compiling page-type.c with a recent compiler produces many warnings,
mostly related to signed/unsigned comparisons. This patch cleans up most
of them.
One remaining warning is about an unused parameter. The <compiler.h> file
doesn't define a __unused macro (or the like) yet. This can be addressed
later.
