[Cooker] urpmi does not handle library split

[Andrej Borsenkow]

urpmi does not (always) handle the case when package is split into package
proper and library. I just had this  with gpm -> gpm + libgpm. With
urpmi --auto-select it tries to update gpm only and this fails because
library (libgpm.so) is no more there.
