LICENSE: event_hdl: fix GPL license version

As spotted by user @songliumeng in GH #2463, there was a mixup between
LGPL and GPL in event_hdl source file: GPL version '2.1' was referenced
instead of '2'. Clarify that this is indeed GPL by making use of the
banner provided in doc/gpl.txt.

This should be backported in 2.8 with 68e692d ("MINOR: event_hdl: add
event handler base api")
