Drop dependency on LGPL-3 libdw for better backtraces
The libdw library is used to get better backtraces, but it is dual-licensed GPL-2 OR LGPL-3 which means that it either:
- restricts all users of GStreamers to be GPL-2
- requires users to be subject to the LGPL-3 provisions
Neither is acceptable for Apertis, so make sure that libgstreamer1.0-0 does not link to libdw1.
