selftests/ftrace: Fix bash specific "==" operator
[ Upstream commit 1e6b485c922fbedf41d5a9f4e6449c5aeb923a32 ]
Since commit a1d6cd88c897 ("selftests/ftrace: event_triggers: wait
longer for test_event_enable") introduced bash specific "=="
comparation operator, that test will fail when we run it on a
posix-shell. `checkbashisms` warned it as below.
possible bashism in ftrace/func_event_triggers.tc line 45 (should be 'b = a'):
if [ "$e" == $val ]; then
This replaces it with "=".
Fixes: a1d6cd88c897 ("selftests/ftrace: event_triggers: wait longer for test_event_enable")
