e `container-essential-services'
always uses the defaults.

It's possible to reference `essential-services' from the operating
system that's passed in, but since it's thunked, the operating system
needs to be defined in two passes to avoid an infinite loop.

* gnu/system/linux-container.scm (container-essential-services): Use
operating-system-essential-services instead of the defaults to allow
overriding the base services.
(containerized-operating-system): Update accordingly.

'nscd-service-type' isn't necessarily present in OS, so we cannot use
the 'modify-services' as it would now error out.  This was happening
with the "guix system docker-image" test in 'tests/guix-system.sh'.

'filter-map' instead of 'remove' + 'modify-services'.
