apt: fix virtual package install version detection (#76781)
* apt: fix virtual package install version detection

Change 4a62c4e3e4 introduced version
matching in installation.

The problem stems from

 if version_installable or version:
     pkg_list.append("'%s=%s'" % (name, version_installable or version))

When the package is a virtual-package, package_status() is returning
the "version_installable" of the package *satisfying* the
virtual-package; but then this is trying to install the
virtual-package with this version pin.

For example, "yaml-mode" is a virtual package satisifed by
"elpa-yaml-mode" (currently 0.0.14-1) and trying to install it fails
with

 $ usr/bin/apt-get -y ... install 'yaml-mode=0.0.14-1'
 ... failed: E: Version '0.0.14-1' for 'yaml-mode' was not found ...

In the case of a virtual-package with nothing installed to satisfy it,
we should just return blank values to allow apt-get to do it's thing.

The tests are updated to install and remove this package.
