fcd: restore support for FUNcube Dongle and Pro+ 

Support for the original FUNcube Dongle used to live in GNU Radio's
gr-fcd module, which was removed in version 3.8. As a result, gr-osmosdr
lost support for both FUNcube Dongle and FUNcube Dongle Pro+.

The gr-fcdproplus out-of-tree module subsequently added support for the
original FUNcube Dongle, meaning that it now supports both types. As a
result, FUNcube support can easily be restored in gr-osmosdr. The
now.
