udev: Add support for setting IFX multiplexer line discipline 

The IFX modem plugin uses a kernel based multiplexer. And to support
different line discipline numbers on different target platforms, allow
them to be specified as option:

KERNEL=="ttyIFX[0-9]*", ENV{OFONO_DRIVER}="ifx", ENV{OFONO_IFX_LDISC}="23"

The extra OFONO_IFX_LDISC option specifies to use line discipline 23
for the multiplexer setup. The number is just an example here and the
correct one will be different.
