Install bc libs when running testsuite
Install bc libs when running testsuite

Newer openssh clients refuse to connect to Gerrit when it doesn't have
bouncy castle libs installed bceause the available encryption methods
are not secure. Fix this by installing the bc libs making ssh clients
happy.

Note that this changes the war to one with working bouncy castle package
urls, it also reindexes after init to make this new war happy.
