update limd and plistbuddy bins for linux, fix pyenv python2 compile on gcc15, prepare idevicebackup stuff

- most of the stuff here is for fixing things on arch/manjaro especially with the libxml2 update
- as well as gcc 15 failing build of python2 since defaults moved to c23
- limd bins are now compiled with libressl 2.2.7 and the .so libs are included (dynamic instead of static since the file sizes will be too large). this should fix potential lockdownd ssl errors
- added idevicebackup stuff for backup/restore on ios 3. backup works, but restore doesnt seem to work so its still disabled for now

restore.sh
