Build the deb package with cmake

Summary:
This diff updates the rule file to use cmake instead of autotools.
The generator is still make, because using ninja requires some more
hacks to the rules file and a recent debhelper version.

Depends on D5802.

Test Plan:

../contrib/release/debian-packages.sh --dry-run <your email>

I set up a PPA to demonstrate it:
