dumpcap: add lcore option
The dumpcap application is reading from ring and writing to
the kernel. By default the EAL init will cause the main thread
to bound to the first lcore (cpu 0). Add a command line option
to select the lcore to use; or if no lcores are specified
then just be a normal process and let the CPU scheduler handle it.
Letting scheduler is likely to work well for process doint
I/O with kernel.

app/dumpcap: support interface name and description
Support setting --ifname and --ifdescr options to record information
in the start of the pcapng interface description block.
Also, records filter (if any) used in the file.
This also makes sure only the interfaces being recorded in
the capture file are in the interface block.

Fixes another bug where dumpcap would always disable promiscious
on exit, even if set by the application.

app/dumpcap: fix storing port identifier
When dumpcap adds an interface, the port was not being preserved. This
results in the structure being initialized and the port field being set
to 0 regardless of what port was actually selected. This unset field is
then used in both the enable and cleanup calls. This could result in the
capture occurring on the wrong interface.

When using dumpcap in container environment or with multiple
DPDK processes, it is useful to be able to specify file prefix.
This version only accepts the long format option used by
other commands. If no prefix is specified then the default
is used.
