[SUSE DEV] [IBS] (Patch4) Disable pull-from-source (PFS)

Copy `no-pfs.patch` from IBS [1] to Git.

We want to keep this as a patch in IBS, since it's really something
specific to how we package Crowbar (no barclamp-git), and not to the
branding.

At the same time, we want to have it in Git so that we see the same
thing as from an RPM installation.

[SUSE DEV] Clean up: Remove unused tests (BDD/ and test/) and doc/

According to Vincent, these are excluded from the barclamp-crowbar RPM
and included only in the barclamp-crowbar-devel RPM.

So we don't really need this patch except to make development from Git a
bit nicer - less noise (eg. when grepping) and avoid possible sources of
confusion from code that we don't use.
