populate: fail if find fails looking for .rsync-filter files

Looking for .rsync-filter files that apply to a file source, a failing
find counted as finding none, and only happened with rsync 3.5.0 and
later.  Like in the shell implementation, find runs before each
transfer with filter files, and its failure stops populate with find's
message, e.g. for a source that's missing, or contains a directory find
can't read, which would also have switched off the check of
insecureLinks.  A signal during find takes effect right after it.
