[Buildroot] [PATCH 3 of 6 v4] pkg-virtual: simplify definition of FOO_VERSION to 'virtual'

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

As mentioned in the e-mail accompanying the introduction of the pkg-virtual
infrastructure [1], the definition of FOO_VERSION is 'strange'.

After the cleanup of single/double dollar signs in inner-generic-package,
the special construction in pkg-virtual is no longer needed and can be
simplified.
