Rather than having to explicitly list each and every driver to disable in a
build, we can use a small python script and the python glob library to
expand out the wildcards. This means that we can configure meson using e.g.
meson -Ddisable_drivers=crypto/*,event/* build
to do a build omitting all the crypto and event drivers. Explicitly
specified drivers e.g. net/i40e, work as before, and can be mixed with
wildcarded drivers as required.

V5:
- add a couple of lines to the doc as an example of using this
V4:
- get pep8/pycodestyle compliance
- simplify getting the root directory
V3:
- added check for correct number of params
- replaced list comprehension with loops for simplicity
- allow running without meson environmental vars set (for easier testing)
V2:
- fixed file suffix
- since it's being called from meson, make this python3 only
- remove use of chdir()
- use '\n' rather than ',' between entries
