e1_input: Use osmo_pcap_lapd if using software LAPD
The e1_input code for PCAP writing uses the Layer3 RSL/OML message and
prepends a fake LAPD header. This means that all frames look like UI
frames in wireshark. In case we use in-kernel LAPD of mISDN, this is
the best we can do. However, in case of software (libosmocore) LAPD,
we can do better, by dumping the real LAPD frames at the interface
between LAPD code and the physical layer.
