Move <boot-parameters> record to a separate file.

Required to avoid a missing dependency error on build-side.

* gnu/system.scm (<boot-parameters>): Move this record, and...
  (system-linux-image-file-name, %boot-parameters-version,
  bootable-kernel-arguments, ensure-not-/dev, read-boot-parameters,
  read-boot-parameters-file, boot-parameters->menu-entry):
  ...these procedures, to...

* gnu/system/boot.scm: ...this new file.

* gnu/machine/ssh.scm, gnu/system.scm, guix/scripts/system.scm,
  tests/boot-parameters.scm: Use new module above.

* gnu/local.mk (GNU_SYSTEM_MODULES): Add new module above.

* gnu/machine/ssh.scm (machine-boot-parameters): Don't private-import
  bootable-kernel-arguments.
