tests: Add a socket timeout
On FreeBSD a races seems to occur between the states socket connecting
and VPP accepting the connection and calling getpeername. The recv_fd
call here will fail with no fds before the VPP process has time to
handle the connection.
Introducing a socket timeout removes this failure on FreeBSD and allows
the test suite to run. Add a timeout on all platforms to try to avoid
this race everywhere.
Type: improvement
