change to freely licensed "stripped" spec file

[jonassmedegaard]

Net::AMQP currently ship with AMQP-licensed spec files. The AMQP license is considered non-free by Debian (and probably others as well) so the BSD-3-clause licensed "stripped" specs should be used instead, if possible.

If you are looking into supporting 0.10 spec, then the AMQP Group do not ship stripped version of that spec, but so does seemingly the Qpid project:

Oh - this licensing issue also affects Net::AMQP::Protocol::v0_8. Seems solvable by simply stripping the non-free spec from the embedded POD.
