Preserve (instead of collapse) arguments in su_monkeysphere_user().autoquote

It is a healthy coding practice to keep each argument separate when
executing system calls, i.e. quote each variable separately instead of
relying on whitespace to indicate argument separation.

Quoting shell-inside-shell is tricky to do right, but not impossible:

Bourne-derived shells treat single-quoting literally, which means that
shell command arguments (i.e. an array of strings) should be safe to
serialize (dual-quote) using these simple rules:

 b) each single-quote inside each string is escaped as '\''
 a) each string is surrounded by single-quotes

This patch applies above single-quote serialization for
su_monkeysphere_user(), and adapts ma/update_users $STRICT_MODES on
line 82 to match.

If serialization routine should turn out to be broken, it will
therefore only affect $STRICT_MODES in ma/update_users badly.  All other
variables passed through su_monkeysphere_user() should not possibly be
treated any worse than previous non-quoting.
