Revert "build *before* OpenNMS constrains memory"

This reverts commit 5b136cdcd5cf1651f44788a2e412bb4b65641a34.
fix extra jar file causing RPM conflicts
make sure we get any stuff from smoke tests
smoke test script cleanups

- get rid of temporary source directory junk
- compile before doing any opennms junk
- die if compile fails
use chrome if it is available
if we build after opennms is starting, we know it will be ready

Conflicts:
	smoke-test/do-smoke-test.sh
chrome does not work either :(
