libwmc: remove it

The WMC protocol was only present on older Panasonic/Verizon devices
from the 2006 - 2011 timeframe. The last device to support WMC was
the UML290 which also supported QMI (which is much more functional).
ModemManager also never used WMC support and it was never significantly
reverse engineered.

So remove WMC code from git; it'll still be in the history if anyone
cares in the future.
