scripts/*.sh.in: Fix signal handler error messages

This includes some fixes to the messages that are displayed when a
signal is caught in makepkg or repo-add:

* Instead of always showing "==> ERROR: TERM signal caught. Exiting...",
  replace "TERM" by whatever signal is actually caught.

* Fix a typo in the SIGERR error message in repo-add ("occurred" instead
  of "occured"). Francois already fixed this for makepkg in 1e51b81c.
