core/linux-aarch64-rc: fixes without bumping pkgrel

Fix drop-ins for mkinitcpio by shipping ALL_config comment out
in inux.preset.  With this line defined, *.conf placed in
/etc/mkinitcpio.conf.d/ are ignored in my testing.

Remove etc/mkinitcpio.d/${pkgbase}.preset from backup array
since having it there will cause breakage of mkinitcpio if
the user modified the preset.  This is due to our hard-coding
the kernel version in the file.  Closes #2029
