cros_unibuild_convert: fix cros-workon usages

According to crbug.com/1078242, we should omit the leading ../ from
CROS_WORKON_LOCALNAME.

This changes the unibuild converter, which generates ebuilds, to
follow that pattern.

For virtual packages, the package was converted away from using
cros-workon.eclass entirely, as we don't really need this
functionality with a virtual package.
