Packaging Bug: test SSL certificates missing from 1.16 PPA

Vincent and Martin made significant contributions leading to this report.

The following tests each contain multiple tests which hang, apparently because the ssl certiciates are missing from /usr/lib/python2.6/dist-packages/bzrlib/tests/ssl_certs as installed by the 1.16 PPA. Copying the certificates from the 1.16 tarball allows the tests to run.

The root cause is that the https test server use some data files (certificates and keys) that are not installed by setup.py.
Under these conditions selftest can be run only from sources.
The test infrastructure is supposed to raise any exception occurring during server building *but* the exception
caused by a missing cert/key file is swallowed by the python SocketServer :-/
