selftests/ftrace: Fix bash specific "==" operator

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 "=".
