Memtest GRUB fixes 
Previous commits to support Memtest86+ 6.00+ split the files into
"memtest" (backwards compatible / new BIOS name) and "memtest.efi"
(new EFI name).  However, the 6.00 non-EFI binaries are now
32/64-bit, and will not work with GRUB's linux16 boot when using GRUB
for BIOS boot.

- Legacy Memtest86+ pre-6.00 will continue to be "memtest", linux16
  (continue to support builds on current Debian stable bullseye)
- Change 6.00+ filename to "memtest.bin"
- GRUB memtest.cfg contains logic for legacy / new bios / new EFI
- Change EFI boot from "chainloader" to "linux", which allows for
  passing command line options to Memtest86+
- syslinux @MEMTEST@ will conditionally be memtest.bin or memtest
- @MEMTEST_BIN@ will conditionally be memtest.bin or memtest, but is
  completely legacy at this point (all internal code paths now check
  for @MEMTEST_DIR@/memtest or @MEMTEST_DIR@/memtest.bin)

Getting complicated, but this logic can be simplified again once we
no longer need to support current Debian stable.

# NOTE: This creates the config used for both grub-pc and grub-efi.
# It also installs loopback.cfg for looback support, which depends upon that
# config. Since loopback support is added unconditionally, this script is
# thus run unconditionally!
# TODO: Add an option to allow disabling loopback.cfg creation? (and thus conditionally run the script)
