libalpm: remove from_md5 and to_md5 from pmdelta_t

The from_md5 and to_md5 fields were a nice extra safety, which would avoid
trying to apply deltas on corrupted package files. However, they are not
strictly necessary, since xdelta should be able to detect that on its own.

The main problem is that it is impossible to compute these informations from
the delta only. So repo-add would not be able to compute the delta entry
based on just the delta file.
