allow for Debian 12 to 13 upgrade

some small changes to allow a user who manually-upgraded their Immich
LXC to Trixie to simply run the update function just the same as those
who installed Immich freshly on Trixie

- check for presence of libmimalloc2.0 and replace with libmimalloc3
- check if Imagemagick is built with a specific CPPFLAG, and trigger a
recompile if it wasn't
