x86/boot/64: Round memory hole size up to next PMD page
The kernel image map is created using PMD pages, which can include
some extra space beyond what's actually needed. Round the size of the
memory hole we search for up to the next PMD boundary, to be certain
all of the space to be mapped is usable RAM and includes no reserved
areas.
