Even if EFI directory is present it may not be populated. kernel-install
part care specifically about xen.cfg file, so check it explicitly. If
grub2-efi is in use, the file wont be there and the script isn't
supposed to do anything.
Fix current EFI boot dir discovery script.
Also, adjust scripts order:
50-dracut generates initramfs in /boot/(efi/)?/$MACHINE_ID/.../initrd
80-grub2 copies it to /boot/initramfs-....img
90-xen-efi copies it to /boot/efi/EFI/qubes/initramfs-....img
Make the above order explicit, rather than relying on xen sorted later
than grub2.

There are multiple places where initramfs can be created:
- /boot/iniramfs-*.img
- /boot/$MACHINE_ID/.../initrd (unused on Qubes, but created by Fedora
scripts)
- /boot/efi/EFI/.../initramfs-*.img
Do not generate all of those from scratch, but try to reuse existing
image (if exists). Since one dracut call may last even 5 minutes, this
change should greatly reduce installation time.

I need to set some flags in order to boot as described here:
https://www.qubes-os.org/doc/uefi-troubleshooting/
My settings look like this:
$ efibootmgr -v
BootCurrent: 0000
Boot0000* Qubes HD(...)/File(\EFI\qubes\xen.efi)p.l.a.c.e.h.o...
which causes awk to get confused and think my $EFI_DIR should be:
/EFI/qubesp.l.a.c.e.h.o.l.d.e.r. ./.m.a.p.b.s. ./.n.o.e.x.i.t.b.o.o.t.
This causes the script to later bail:
if [ ! -d "$EFI_DIR" ]; then
# non-EFI system
exit 0;
fi
So my xen.cfg did not get new entries when installing dom0 kernel packages.
The entry may be already present for example when reinstalling package,
or calling the script multiple times (which apparently is the case
during system installation).
In non-EFI installation /boot/efi/EFI/qubes may not exists. In this case
do not try to touch (non-existing) files there.
