setup: include shell completions in sdist

- move build directory of the shell completions from /build/shtab to
  /completions due to an sdist restriction of setuptools and MANIFEST.in
- recursively include the /completions directory in MANIFEST.in
- update data_files path in setup.py (for inclusion in wheels)
- update .gitignore
