pkg: dependencies to specific package checksum

When package is installed from commandline, we should always
install that specific instance of package (never favor repository
version if it has difference identity). Otherwise we might not
always end-up installing the .apk given on command line. The
dependency is now against specific checksum identity (marked
with >< dependency comparison). Fixes #492.
