gmessages: Clarify documentation about aborting on fatal log levels
Clarify that we actually raise SIGTRAP rather than calling abort(). We haven’t called abort() since about 2011, when commit a04efe6a changed the logic to use SIGTRAP to make it possible to skip past fatal log messages in the debugger if they weren’t relevant to the problem being debugged.
