configure: Make sphinx-build version test work on recent versions
On Fedora: `/usr/libexec/sphinx-build --version` outputs `sphinx-build 1.7.2`. In bindir we actually have sphinx-build-2 and sphinx-build-3 (python2 and python3 versions), which output `sphinx-build-2 1.7.2` and `sphinx-build-3 1.7.2` respectively. Dunno what version others are using but at least this change should works for most versions I suppose.
