There is UEFI firmware popping up in the wild now that implements stricter permission checks using NX and write protect page table entry bits. This means that firmware now may fail to load binaries if its individual sections are not page aligned, as otherwise it can not ensure permission boundaries. So let's bump all efi section alignments up to 4k (EFI page size). That way we will stay compatible going forward. Unfortunately our internals can't deal very well with a mismatch of alignment between the virtual and file offsets, so we have to also pad our target binary a bit.
