Page alignment is needed for the address in memory, not for the offset
inside the file on disk; since section virtual addresses in PE files
are always page-aligned the memory address is never a problem. The
only problem comes from the alignment of the data inside the PE file,
and this is where we only need block-size alignment to make mmap
possible.
