hackrf_transfer: Don't skip preload stats in RX

Fixes a bug introduced in 8a9af7a: Statistics skipped for initial
buffers not only when preloaded in TX mode but also in RX mode with no
preloading.

The total bytes transferred may appear inflated in RX mode when
receiving a small number of samples with -n, but the stats represent
data transferred over USB, some of which may have been discarded by the
host.

hackrf_transfer: simplify hardware sync mode logic

The -H option now requires no argument.

hackrf_transfer: send signal to own PID

Instead of sending a signal to the process group, get our own process ID
and send the signal to it. This fixes a bug that prevented termination
when called from a script.

Merge remote-tracking branch 'origin/master' into tx-transfer-sizing

Pad the last data in a transmission to the next 512 byte boundary.
