[PATCH v8 7/8] test/pcapng: skip test if null driver missing

[Stephen Hemminger <stephen@networkplumber.org>]

The pcapng test requires the net_null driver to create a virtual
device. If the null driver is excluded from the build, the test
fails with:

 RTE>>pcapng_autotest
  + ------------------------------------------------------- +
  + Test Suite : Test Pcapng Unit Test Suite
 Failed to create vdev 'net_null0'

Add net_null to the meson build dependency list for the test so
that it is automatically skipped when the driver is not available.
