emerge: add --autounmask-keep-keywords option (bug 622480)

The option prevents --autounmask from making changes to
package.accept_keywords. This option does not imply
--autounmask-keep-masks, so --autounmask is still allowed
to create package.unmask changes unless the
--autounmask-keep-masks is also specified.
