pcr: Add prelimirary userspace support for the xtrx SDR

Caveats:
- There is no package for xtrx-linux-pcie-drv yet
- The liblms7002m, libxtrx and libxtrxdsp are installed in
  /usr/local/
- While gqrx can be launched, I didn't manage to receive
  commercial FM stations with it yet. That may be due to:
  - my hardware setup (antennas, etc) which is far from
    being obtimal
  - my software setup (i686 hasn't been reported to work
    yet)
  - Wrong parameters in gqrx: the device seem to be other
    and the device string seem to be "xtrx", but other than
    that I didn't have a good enough waterfall to verify
    that it is receiving something.
