util-lib: drop json parser

This was used by the dkr logic, which is gone now, hence remove this too.
Should we need it one day again the git history never forgets...

Note that this only covers the JSON parser. The JSON generator used by
"journalctl -o json" remains, as its much much simpler and requires no
infrastructure except printf() and the most basic escaping.
