util: add shell_maybe_quote() call for preparing a string for shell cmdline inclusion

If necessary the passed string is enclosed in "", and all special
characters escapes.

This also ports over usage in bus-util.c and job.c to use this, instead
of a incorrect local implementation that forgets to properly escape.
