error out on failing libapparmor test_multi tests

This patch adds a check-local target to libapparmor/testsuite/Makefile.am
that checks the logfile generated by the test_multi tests
(libaalogparse.log) and errors out if
- the logfile doesn't exist (which might mean that dejagnu isn't installed
- the logfile contains 'ERROR'

This isn't the best solution I can imagine, but it's the only/easiest
way I found that doesn't need changing of autogenerated files.


Also extend clean-local to delete libaalogparse.{log,sum}

Finally, add test_multi/testcase_syslog_read.err (empty file) to avoid
make check fails.
