Libguestfs - Nov 2019 - [PATCH] tests: rhv-upload: Require nbdkit python plugin

With recent nbdkit the skip test fails the rhv-upload test skip:

    $ nbdkit python3 --version
    nbdkit: error: cannot open plugin 'python3':
    /usr/local/lib/nbdkit/plugins/nbdkit-python3-plugin.so: cannot open
    shared object file: No such file or directory

It seems that the python plugin is always installed as
nbdkit-python-plugin.so, so the correct test now is:

    nbdkit python --version

This may not work with older version of nbdkit, but I'm not sure this is
relevant now.

This will break for people using
./configure --with-virt-v2v-nbdkit-python-plugin=...

We could probably drop that option, but that complicated RHEL.
Otherwise the rather more complicated patch attached is needed.

This looks like what we did in libguestfs for a couple of tests, so
IMHO it is OK.

Another possible approach is to output VIRT_V2V_NBDKIT_PYTHON_PLUGIN
(and any other variable needed in shell scripts used only at
build/test time) to a new config.sh file, and source that as part of
the TEST_FUNCTIONS stuff.
