liblog: enable tests accidentally disabled

Some tests were meant to be run with logd only and were ifdef'ed based
on USING_LOGGER_DEFAULT.  Unfortunately a previous change removed the
appropriate #define, so these tests weren't being run at all.  They
passed multiple times on CF, so they should still be stable.

Except for one test for __android_log_event_list.  We removed that
struct, so this change removes the test as well.

Test: liblog-unit-tests on CF (5 runs)
