MDEV-7996 : CURRENT_USER definer does not replicate for triggers

Browse Source 
THD's lex->definer initially holds "*current_user" for CURRENT_USER().
As a result when wsrep tries to create the trigger query, it incorrectly
uses "*current_user". Fixed by calling get_current_user() to get the
real current user.

Merged galera_create_trigger.test from github.com/codership/mysql-wsrep.
