package/libopenvg: rename the _HAS and _PROVIDES variables

The basic rule for a package is to have its options named
after the package name. There is no reason this should not
also be the case for virtual packages.

Besides, renaming the package will allow us to switch libopenvg to use
the soon-to-be-introduced virtual-package infrastructure.
