Log Message:
jsexec: don't call lprintf() from the SIGTERM/SIGHUP handlers

break_handler() and recycle_handler() logged "Terminated/Recycled Locally"
via lprintf(), which locks output_mutex. A signal arriving while the main
thread was inside lprintf() deadlocked the process on that mutex, so a
long-running jsexec service (IRC bot, ircd) could ignore SIGTERM until
systemd's stop timeout SIGKILLed it. Reproduced in 15 of 40 SIGTERMs to a
script that logs continuously; 0 of 40 with this change.

The handlers now only record the signal and set the flags; the messages
are logged from the main thread once js_exec() returns.
