libalpm/add.c,trans.c : cleanup of requiredby handling.

This patch cleans up and fix the _alpm_trans_update_depends function
and ensure that all requiredby fields are filled in case of multiple satisfiers
(previously, the handling of mutliple satisfiers in that function was inconsistent).

This makes a special case handling of requiredby in commit_single_pkg() obsolete,
and so allows cleaning that code as well.

Also fixed upgrade056 pactest because :
1) the requiredby fields were wrong, and this wouldn't happen with the fixed _alpm_trans_update_depends().
2) this is a very unusual case anyway (and handling all corner cases combined to a broken database
  seems nearly impossible to achieve).
