[PATCH] doc/conf.py: Remove _static from html_static_path

[W. Trevor King]

Avoid:

  $ make HAVE_SPHINX=1 sphinx-html
  python ./doc/mkdocdeps.py ./doc doc/_build doc/docdeps.mk
  sphinx-build -b html -d doc/_build/doctrees -q ./doc doc/_build/html
  Making output directory...
  WARNING: html_static_path entry '/home/wking/src/notmuch/notmuch/doc/_static' does not exist

because we have no static source in doc/_static.
