uhd: Set default Tx sampling to 4 sps 

The majority of GSM host platforms are capable of operating with
the 4x oversampled modulator, which justifies the new default
setting. The small number exceptions (e.g. Raspberry Pi) can still
use the lower complexity 1 sps modulator with the '-s 1' command
line option if required.
