mem.py: fix SIGBUS when accessing file mapped by mmap_syscall

this fixes SIGBUS errors caused by accessing beyond the end of a
file but still in the last page of the file, which is a valid thing to
do, except that we have to account for host pages having a different
size than emulated pages and map zeros to fill out the rest of the
emulated page.
