gnu: system: Add Linux container module.
* gnu/system/linux-container.scm: New file. * gnu-system.am (GNU_SYSTEM_MODULES): Add it. * gnu/system.scm: Export 'operating-system-etc-directory', 'operating-system-boot-script', 'operating-system-locale-directory', and 'file-union'. (operating-system-boot-script): Add #:container? keyword argument. (operating-system-activation-script): Add #:container? keyword argument. Don't call 'activate-firmware' or 'activate-ptrace-attach' when activating a container.
