tools/resolve_btfids: Check objects before removing
[ Upstream commit f23130979c2f15ea29a431cd9e1ea7916337bbd4 ]
We want this clean to be called from tree's root clean
and that one is silent if there's nothing to clean.
Adding check for all object to clean and display CLEAN
messages only if there are objects to remove.
