patch 9.1.1193: Unnecessary use of STRCAT() in au_event_disable()

Problem: Unnecessary use of STRCAT() in au_event_disable(). STRCAT()
seeks to the end of new_ei, but here the end is already known.
Solution: Use STRCPY() and add p_ei_len to new_ei. Also fix a typo in a
comment. Add a test that 'eventignore' works in :argdo
(zeertzjq).

closes: #16844
