add: support for virtual meta packages
implements 'apk add --virutal metaname dep1 dep2...' where metaname will be an empy meta package with dep1 and dep2 as dependencies. This is useful to prevent abuild to add each makedepend to world which causes some headache when it comes to unintalling them after sucessful build.
