File findfplistexclude.diff of Package rpm.SLE_11

Allow an "exclude" parameter for rpmdbFindFp, specifying a header
that is to be excluded in the match. Used to speed up package erase
operations.
Also fixes the skipDir problem that made rpm incorrectly delete
files even if another package still references them.
