Make it honor fflag to ignore fts_read errors, but stop deleting from that directory because no further progress can be made. When building a kernel with a high -j value on a high core count machine, during the cleanobj phase we can wind up doing multiple rm -rf at the same time for modules that have subdirectories. This exposed this race (sometimes) as fts_read can return an error if the directory is removed by another rm -rf. Since the intent of the -f flag was to ignore errors, even if this was a bug in fts_read, we should ignore the error like we've been instructed to do.
