[REVIEW 06/10][linux] UBUNTU: [Packaging] Generate linux-doc for only the primary variant

[Seth Forshee]

Even though the doc package is generated as SRCPKGNAME-doc in the
control stub, we're really only set up to have a single doc
package. Therefore split out linux-doc into its own control stub,
which will be included in the control file for only the primary
variant.
