test: delay watchdog checks in emacs.

Instead of checking immediately for the watched process, delay a
minute, or in the case that process-attributes returns nil, for two
minutes.  This is intended to cope with the case that
process-attributes is unimplimented, and returns always returns nil.
In this case, the watchdog check is the same as the two minute limit
imposed by timeout.
