    python-smartpm: use md5 as the digest for rpm_sys channel
    
    Use md5 sum instead of mtime as the "digest" method for rpm_sys channel.
    The digest is used to determine if the channel has been updated. It was
    found out that mtime was not a reliable digest. On some systems mtime
    of the rpm db does not get updated after every transaction if transactions
    (smart install / remove commands) are fired in quick succession. As a
    consequence smartpm cache and rpm db get out of sync.

+channels/rpm_sys: use md5sum instead of mtime as the digest
+
+Use the internal getFileDigest() function (which defaults to md5) instead of
+mtime for getting the file digest. On some systems mtime proved to be
+unreliable because of delayed update. This caused smart to miss rpm db updates
+and thus get its understanding of installed packages out of sync.
