prereqs should be involved for dependency resolving

Pre-requires: Requirespre/Requirespost/PreReq should be considerred for
dependency resolving

Example:
  fake.spec contails:
    Requires(post):   systemd
    Requires(preun):  systemd
    Requires(postun): systemd

If systemd does not available in remote repo and localrepo, depanneur
should report expansion error, instead of executing building
