osbuilder: Remove gentoo rootfs-builder
As the gentoo rootfs is not tested in our CI, we can't guarantee it actually works as expected. Whenever we have someone willing to maintain this rootfs we can have it added back, and also add a CI job to test it altogether, avoiding then any possible regression. Fixes: #2144 Signed-off-by: Fabiano Fidêncio <fabiano.fidencio@intel.com>
