buildrpm: bump bundled docutils version to 0.14 when building for centos{5,6}

when building rpm packages for centos 5 and 6, we bundle a mercurial-specific
version of docutils in /opt/python-hg/lib/python2.7/site-packages/docutils

Let's bump the embedded docutils version from 0.12 (released in 2014) to
0.14 (latest as of today)
