x86/efi: Drop alignment flags from PE section headers

commit bfab35f552ab3dd6d017165bf9de1d1d20f198cc upstream.

The section header flags for alignment are documented in the PE/COFF
spec as being applicable to PE object files only, not to PE executables
such as the Linux bzImage, so let's drop them from the PE header.
