builddeb: new script for building a deb package

Future work will allow us to use docker to build debs.

Right now this doesn't install any config files. I plan to do that as
a followup, but getting something basic and working checked in seems
like more of a priority than getting everything done in one big step.

This also does not create a source deb yet. I haven't looked into that
process.

Note that this declares incompatibility with the `mercurial-common`
package. It's typical for debian packages to be split between
architecture-independent bits and native bits, meaning the python bits
downstream live in mercurial-common and the c extension bits live in
mercurial. We don't do that because we want to (ideally) give users a
single deb file to install.
