POSIX: ScopedMmap length refinement

9d26012e9c73 relaxed the requirement on ScopedMmap such that the length
of the region supervised no longer needed to be provided as a round
number of pages. This was accomplished by internally rounding up the
provided length to a page length. Unfortunately, this made

ScopedMmap::len() return something other than the passed-in length,
which is undesirable. This change makes ScopedMmap store the passed-in
length internally, making it available unmodified via the accessor, and
rounding it up to page length at internal points of use.
