packaging: add make target for linux wheels
Having linux wheels is going to helps system without compiler or python-dev
plus speed up the installation for everyone.
I followed the manylinux example repository
https://github.com/pypa/python-manylinux-demo
to add a make target (build-linux-wheels) using
official docker image to build python 2 linux wheels
for mercurial. It generates Python 2.6 and Python 2.7 for both
32 and 64 bits architectures.
I had to blacklist several test cases for various reasons:
* test-convert-git.t and test-subrepo-git.t because of the git version
* test-patchbomb-tls.t because of warning using tls 1.0
It's likely because the docker image is based on centos 5.0 and
openssl is outdated.
