Fabiano Fidêncio 06fae29f49 osbuilder: Remove centos rootfs-builder 
As the centos rootfs is not tested in our CI, we can't guarantee it
actually works as expected.

Whenever we have someone willing to maintain the rootfs we can have it
added back, and also add a CI job to test it altogether, avoiding then
any possible regression.

Fixes: #2140
