--plugin-add arguments causing server start to fail on freebsd

[Patrick Crews]

tests that use --plugin-add are failing on freebsd as follows:

cat server0.err
Can't open shared library
'/usr/home/pcrews/repos/drizzle/plugin/.libs/libcsv_plugin.so'
(errno: 2 Cannot open "/usr/home/pcrews/repos/drizzle/plugin/.libs/libcsv_plugin.so")
Couldn't load plugin library named 'csv'.

Try to run the csv suite on freebsd (it uses --plugin-add=csv), you will observer drizzletest failing as it can't find the server / nor will server-shutdown find a server to shutdown.

NOTE: This appears to happen for all plugins when --plugin-add=$plugin is used, not limited to CSV (realized my wording could make it seem tied to one plugin)

Need to research this a bit more, found some information that points to other issues.

By coincidence the two suites I tried to use are no longer built by default (csv + filesystem_engine) :-/
My mistake.

Tests are executing for me with both test-run.pl and dbqp.py
