passt/test/perf/pasta_udp
David Gibson a832a44e67 tests: Explicitly list test files in test/run, remove "onlyfor" support 
Currently test/run uses wildcards to run all of the tests in a directory.
However, that wildcard list is filtered down by the "onlyfor" directives
in the test files... usually to a single file.

Therefore, just explicitly list the files we *really* want to run for this
test mode.  This makes it easier to see at the top level what tests will
be executed, and to change that list temporarily while debugging specific
failures.

This means the "onlyfor" directive no longer has any purpose, and we can
remove it.  "onlyfor" was also the only used of the $MODE variable, so we
can remove that too.
