services: shepherd: Make /run/booted-system a symlink to the store item.
Fixes <https://bugs.gnu.org/46767>. Previously /run/booted-system would end up referring to /var/guix/profiles/system-NNN-link; consequently, the booted system would not be GC-protected. * gnu/services/shepherd.scm (shepherd-boot-gexp): Call 'canonicalize-path' instead of 'readlink'.
