install-ansible: unconditionally install build-essential

Deployment to the new Jammy bridge host is failing because it can't
build netifaces for Python 3.10.  Upstream doesn't have a wheel --
this must not fail in the gate because we setup the testing bridge
node to use our wheel cache.

We should unconditionally install this for maximum flexiblity when
deploying fresh hosts.
