[JOBS] Fix wait regression where it does not wait for all jobs
The sigsuspend patch broke wait by making it return after just one job has completed. This is because we rely on pendingsigs to signal work and never clear it until waitcmd finishes. This patch adds a separate gotsigchld for this purpose so we can clear it before we start waiting. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
