smpl_buf: Move it to device/common and create libdevice_common.la

Since in next commit osmo-trx-lms starts using smpl_buf.cpp, it seems
some automake step doesn't like including a cpp file twice from a
different directory, since race conditions can occur building it.
Instead we define the dependency by first building a static lib and then
using it on each libdevice.la (one per device type).

We already do the similar under arch/ subdir, where we have a common/
subdir and then one subdir and lib per architecture.
