pdu_queue must be non-blocking in order to avoid the ue or enb to block in the event of a memory leak and the buffer pool running out of buffers. In that case, the null return shall be handled properly and error logged. This commit restores commit c4c44c33f4

MAC PDUs are default logged using the MAC log. So this gives
hex prints, etc. without having to manually set the logger for each
PDU.

pcap: make public interfaces thread-safe and handle fopen returning nullptr
...
the previous patch only introduced a thread-safe queue between
PHY workers (writers) and PCAP writer thread (consumer).
However, it is also required to protect the ctor (and close()) to
prevent corrupted PCAP files.
The patch also correctly handles the case where the PCAP couldn't
be openend for writing and doesn't start the thread.
