This allows containers created by "guix environment -CN" or by
"guix system container -N" to talk to the host nscd.

* gnu/system/file-systems.scm (%network-file-mappings): Add
"/var/run/nscd".
* gnu/build/shepherd.scm (default-mounts)[nscd-socket]: Remove.
* gnu/system/linux-container.scm (container-script)[nscd-run-directory]
[nscd-mapping, nscd-os, nscd-specs]: Remove.
[script]: Filter out from SPECS bind-mounts where the device does not
exist.

linux-container: Check if nscd run directory exists when container is run.
* gnu/system/linux-container.scm (containerized-operating-system):
(container-script): Check for existence of the host nscd run directory in the
container script. This check should be run when the container is started, not
when the container script is created.

linux-container: Compute essential services for THIS-OPERATING-SYSTEM.
Previously, the 'essential-services' would correspond to the initial,
non-containerized OS.  Thus, all the file systems removed in
'container-essential-services' would actually still be there because the
essential services would be computed on the non-containerized OS.

This is a followup to 69cae3d335.

* gnu/system/linux-container.scm (container-essential-services): Call
'operating-system-default-essential-services' to get the baseline
services.
(containerized-operating-system): Pass THIS-OPERATING-SYSTEM, not OS, to
'container-essential-services'.
Add a dummy root file system to 'file-systems'.
(container-script)[mountable-file-system?]: New procedure.
Use it.

linux-container: Do not add %CONTAINER-FILE-SYSTEMS to Docker image OSes.
Previously, 'guix system docker-image' would end up providing an OS that
would try to mount all of %CONTAINER-FILE-SYSTEMS as well as /gnu/store,
which is bound to fail in unprivileged Docker.

This patch makes it so that 'guix system container' still gets those
file systems, but 'guix system docker-image' doesn't.

* gnu/system/linux-container.scm (containerized-operating-system): Add
 #:extra-file-systems parameter and honor it.  Do not include
 %STORE-MAPPING and SHARED-NETWORK-FILE-MAPPINGS.
(container-script): Add %STORE-MAPPING and optionally NETWORK-MAPPINGS
to MAPPINGS and pass #:extra-file-systems.

service.

remove nscd service and map host's /var/run/nscd if it exists.
(container-script): If network is to be shared with the host, do not create
network namespace.
* guix/scripts/system.scm (system-derivation-for-action): Add
#:container-shared-network? argument.
