net/bitlbee: no need for Python anymore

One more Python 2 cleanup.

Stuart pointed out that previous versions of bitlbee didn't generate
help.txt in the release tarball, hence the need for Python historically.

There's one more Python script in this port, but it doesn't seem to be
used for anything in the package.
