With this patch, users not in the NACM admin group and a login shell set
to clish can now log in to the CLI. Prior to this change only members
of the UNIX group 'wheel' could open the klishd socket.
The patch adds another group, 'sys-cli', which acts as a capability for
users. An admin user (member of the admin group) will now be member of
both the UNIX 'wheel' and 'sys-cli' groups. A non-admin user that has
shell set to 'clish' will only be member of the 'sys-cli' group. Other
users will not be mapped to any UNIX group and have only permissions set
in NACM.

This fixes a serious security regression introduced late in the v24.04
release cycle. The root cause is the placement of the shadow file in
the rootfs overlay, which causes any changes made by the Buildroot
setting BR2_TARGET_ENABLE_ROOT_LOGIN to be discarded/overwritten just
before creating the squashfs image.
The fix in this commit relocates all files from b4eb450 to the skeleton
in Infix, package/skeleton-init-finit/skeleton/etc, which is one of the
first packages to be installed when starting a build.
