testlib: Add selftests for -v1 and -v2 command-line switches.

These tests don't have their own source code but rather reuse the
counting selftest with additional command-line options.

Note that currently the -v1 switch only changes the plain text output,
and the expected xml output is identical to that of the counting test.
This may change in the future however.

This commit also restores a couple of lists to alphabetical order, where
the findtestdata selftest was not sorted into the list correctly.
