liblog: test: __android_log_error_write accuracy

(cherry pick from commit 5cecedc6e8d5559213220b4dae993f277801433a)

Add a test to confirm exact expected content using the testframe
setup for the events log handler. Remove dependency on 512 truncation
in liblog->
android_errorWriteWithInfoLog__android_logger_list_read__data_too_large
to something more liberal.
