solver: consider virtual provides to exclude non-provides transitively

this fixes package selection when a 'real' package exists, but would
need to be provided by another package with 'virtual provides'.

In current package database this can happen with postgresql which is
also provided by postgresql-bdr. Normally postgresql would be satisfied
by postgresql, but if any package depends on postgresql-bdr and there's
no versioned dependency on postgresql this will help apk figure out
that postgresql-bdr should be used.
