emerge: disable --autounmask-license by default

Disable --autounmask-license by default, in order to limit user
exposure to risks associated with package.license changes.
The changes that this option suggests are only intended to be
accepted when a user has made a conscious decision to accept
the corresponding license(s). Creation of package.license
changes introduces a risk that users may erroneously accept the
changes due to some kind of accident or misunderstanding,
rather than due to conscious decisions about licenses.
These risks provide motivation to disable --autounmask-license
by default. The --autounmask-use option will remain as the
only autounmask option that is still enabled by default.

The unit tests demonstrate interactions between --autounmask
and --autounmask-license options. The --autounmask option
enables --autounmask-license unless --autounmask-license=n
has been specified. If --autounmask=n is used to disable
autounmask, then --autounmask-license=y has no effect.
