All versions, trivial PcMemtest provision for mint-21-release iso

[SimonIremonger]

Please look at including on the mint-21 release ISO image both:- /boot/pcmemtest.bin [replacing, or in addition to memtest86+.bin for legacy-booting memtest] This seems to be better to me. /boot/pcmemtestx64.efi IMPORTANT this now allows FOSS memtest to work on EFI systems from the linux mint boot image, put "Memory Test" back in the EFI boot menu list with a 'linuxefi' or equivalent boot entry.

Both these files can be found from the Ubuntu 22.04 'pcmemtest' package, which is an improved fork of older memtest86+, which has been accepted back into FOSS memtest project now.

Note, r.e. installed 22.04 systems, that 'pcmemtest' package itself attempts to detect EFI booting is available, and thus doesn't correctly set up bootability of pcmemtest.bin for legacy-booted systems, given that the new installer always sets up hybrid bootablity with EFI as well. This scripting-oversight does not, in any way, preclude including pcmemtest on the Linux Mint 21 release .iso which would be a very low regression-potential addition that doesn't affect installer or installed-systems in any way.

Add to the roadmap for consideration in Mint 21.1.

some infos: pcmemtest was not developed anymore and package will be removed as was merged into memtest86+ v6 memtest86+ v6 is developed by initial memtest86+ developer + pcmemtest developer and another; started on pcmemtest, added some features missed in pcmetest that was present in older memtest86+ and other improvements/fixes v6 beta3 is in debian experimental for now (maintained by me and pcmemtest maintainer), actually v6 it is in feature freeze and final release will be released probably in 4-6 weeks. any help to test/improve memtest86+ v6 package is appreciated on final release we'll migrate to debian unstable and after migration to testing if there isn't important issue I want do a backport to bullseye and jammy
