Alexander Graf a51f953f4e mkimage: Align efi sections on 4k boundary
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.

This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.

See the file NEWS for a description of recent changes to GRUB 2.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.

There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please
