Hi!

While working on the “reproducible builds” effort [1], we have noticed
that python-babel could not be built reproducibly.

The attached patch makes build timestamp independent from the timezone
and remove the name of the build system locale from the documentation.
It also fixes the documentation, which claims the default value of some
function parameters are <the build system locale>, whereas it is the
locale of the user running python-babel.

Once applied, python-babel can be built reproducibly in our current
experimental framework.
