  Fix Autotools failure requiring README (oops)

Automake requires README to exist by default, but it was renamed to
README.rst recently.  Thus, change Automake strictness to `foreign'
for README to be optional, and distribute README.rst explicitly.

Although `foreign' strictness don't require any of the README, INSTALL,
COPYING, etc. files, it still includes them if available, so the
distribution still includes them.
