x86/EFI: adjust installation logic
We should always install xen.efi into /usr/lib64/efi/; installation
into /boot/efi/efi/$(EFI_VENDOR) remains dependent upon specifying
EFI_VENDOR.

x86/EFI: fix interrupt and fault handling during runtime services calls
The missing piece was the setting up of an accessible GDT prior to
switching page tables (and reverting to the original setting after
having established the normal page tables again afterwards).

The SuSE version of gcc produces a non-standard section named
.comment.SUSE.OPTs, but the PE32+ handling in binutils can't really
deal with any section to be placed at virtual address zero (and not
needing to be loaded). Even if binutils did, at least the UEFI
implementation in EDK 1.06 doesn't look at the section characteristics
at all, and hence would attempt to load such a section, and fail or
corrupt other data.
