[RFC 2/6] pdump: handle primary process exit

[Stephen Hemminger <stephen@networkplumber.org>]

If primary process exits, then it is not possible (or needed)
to cleanup resources. Instead just exit after closing the
capture file.

Bugzilla ID: 1760
Fixes: a99a311ba101 ("app/pdump: exit with primary process")
