When canbusload is executed without bit rate, it exits with an exit
code of 1 and prints help, but without explaining why. Users cannot
know what was wrong. When other errors occur, though, canbusload
prints an error message along with the help.
Print an error message when bit rate is not given or "@" is not found.

For j1939acd.c, it was using s.sig_term as a boolean key to exit from
the while loop. This commit replaces a.sig_term with a.signal_num,
which holds the signal it received.

canfdtest.c was effectively raising the received signal again to run
the default signal handler. This has been declined by the maintainer
because it's over-engineering. This commit replaces it with the
method proposed by the maintainer.

canlogserver.c was using a non-safe function, exit(3), in the signal
handler. This commit replaces it with the way other programs in
can-utils are using; set running = 0 to exit from the while loop.
