meta-agl-profile-core: add patch for systemd-udevd SECLABEL crash
Add a patch to fix a systemd-udevd crash when parsing SECLABEL tokens
in udev rules. The issue was introduced by a rewrite of the rules parser
in systemd v243. The patch will be upstreamed to hopefully go into one
of the v243.x systemd-stable releases.
