data: Add Tanglu distribution information

Add information about Tanglu 1.0 'Aequorea' and Tanglu 2.0 'Bartholomea'.
Welcome, Tanglu.
debian/python3-apt-dbg.files: Fix pattern for kFreeBSD

We previously moved all files containing a "d", but kfreebsd contains
a "d" itself, so the build failed.
tests/test_policy.py: Disable, uses system state (FTBFS on ppc64)

Disable the tests until we can fix them properly.
tests/data/aptsources/sources.list.testDistribution: Add tanglu
tests/test_policy.py: Fix comment to conform to PEP8
Release 0.9.3
debian/rules: Do not run dh_sphinxdoc -a

Running dh_sphinxdoc -a causes the build to FTBFS on buildds, because
the sphinx documentation is not built. Only run dh_sphinxdoc if we
are building the sphinx documentation.
