* gnu/packages/version-control.scm, gnu/packages/vim.scm,
gnu/system.scm, gnu/system/dmd.scm, gnu/system/shadow.scm,
gnu/system/vm.scm: Change references to (gnu packages system) to (gnu
packages admin).
This is a followup to commit 4aeea89.
* gnu/packages/gettext.scm (gettext): Rename to...
(gnu-gettext): ... this. This is used to work around the circular
dependency introduced in commit c42a4b7, which users with a #:renamer
cannot cope with.
* gnu/packages/acl.scm, gnu/packages/attr.scm, gnu/packages/cdrom.scm,
gnu/packages/fdisk.scm, gnu/packages/gkrellm.scm, gnu/packages/glib.scm,
