[bug#61750] [PATCH] gnu: shepherd: Build Shepherd from git.

FTR, i've made progress, and i think i'm back to my original routine.

what i was missing is adding this to my guix .envrc:

export GUILE_LOAD_PATH=~/workspace/guix/shepherd/.guix/modules:$GUILE_LOAD_PATH

this then enables the following:

(define *parent-shepherd-package* (@ (shepherd-package) shepherd))

with this shepherd package i can once again start a `guix system vm` with all the changes in my shepherd checkout compiled in, and with a bearable turnaround time.

note that this was not suggested in the README. i'll keep an eye on updating the docs to help others getting into shepherd hacking.

thanks for your patience and help Ludo!
