[PATCH v5 3/3] mkimage: Clarify file alignment in efi case

[Alexander Graf <agraf@suse.de>]

There are a few spots in the PE generation code for EFI binaries that uses
the section alignment rather than file alignment, even though the alignment
is really only file bound.

Replace those cases with the file alignment constant instead.
