Some unit tests has dependency on RING PMD,
so this patch is trying to fix those and other
closely related issues.

1)pdump, latency, bitrate, ring PMD and test_event_eth_tx_adapter
unit tests are dependent on ring PMD, so compile those
tests only when ring PMD is enabled else ignore.

2)get rid of make file error which was added by bond unit test
for ring PMD disabled case which is not necessary.

3)Tx adapter UT is dependent on RING PMD, but it was
observed that it was missing from the run in meson
build, so added it. TX adapter UT uses 'sw event and
'null' pmd drivers, so for shared builds the drivers .so
path has to be passed to the test args of meson UT run.

Confirmed build now works with disable_drivers=net/ring

Unfortunately, other parts fail if other drivers are similarly disabled,
but that is for another patchset (and probably release!) to fix.
