During build time mask only those feature/services that are disabled excplicitly (#13283)

Browse Source 
What I did:
Fix : #13117

How I did:
During build time mask only those feature/services that are disabled explicitly. Some of the features ((eg: teamd/bgp/dhcp-relay/mux/etc..)) state is determine run-time so for those feature by default service will be up and running and then later hostcfgd will mask them if needed.

So Default behavior will be

init_cfg.json.j2 during build time make state as disabled then mask the service
init_cfg.json.j2 during build time make state as another jinja2 template render string than do no mask the service
init_cfg.json.j2 during build time make state as enabled then do not mask the service

How I verify:
Manual Verification.
