Add control files for utopic

Summary:
Very straightforward. Basically a copy-paste job of trusty,
with a couple of bumps of package versions (i.e., the default boost is
now 1.55 instead of 1.54).

Test Plan:
Set up an utopic VM, follow the build directions on the wiki
for trusty, use the packaging script to build an utopic deb. Move the
deb onto a clean utopic VM, use `gdebi` to install it + dependencies
(and nothing else), see that it runs and works fine.
