license: Drop adding RRECOMMENDS for license packages

This changes behaviour when LICENSE_CREATE_PACKAGE is in use. Packages
no longer have RRECOMMENDS adding to them.

It was highlighted that this doesn't apply to PACKAGES_DYNAMIC, nor can
it easily be made to do so. There is also a much easier way to handle this
which is:

IMAGE_INSTALL_COMPLEMENTARY += "*-lic"

which works on a per image basis and doesn't change the underlying
package dependencies. I propose we switch to this instead.
