core/socket: shorten/reword message about restarted sockets

log_unit_warning() already prints the full unit name, so we don't need to say
that it is a socket unit. And in technical messages articles like "the" are
generally skipped to make the messages shorter. Use simpler tense and simpler
wording.

Example from log: fedora.local systemd[1]: systemd-initctl.socket: Socket unit
        configuration has changed while unit has been running, no open socket file
        descriptor left. The socket unit is not functional until restarted.
This is just too wordy and says "socket" four times.
