Rename (gnu build linux-initrd) to (gnu build linux-boot).

* gnu/build/linux-initrd.scm: Rename to...
* gnu/build/linux-boot.scm: ... this.
* gnu-system.am (GNU_SYSTEM_MODULES): Adjust accordingly.
* gnu/build/activation.scm, gnu/build/vm.scm, gnu/services/base.scm,
  gnu/services/dmd.scm, gnu/system.scm, gnu/system/linux-initrd.scm,
  gnu/system/vm.scm: Adjust accordingly.
