jobs: Fix waitcmd busy loop
We need to clear gotsigchld in waitproc because it is used as
a loop conditional for the waitcmd case. Without it waitcmd
may busy loop after a SIGCHLD.
This patch also changes gotsigchld into a volatile sig_atomic_t
to prevent compilers from optimising its accesses away.
Fixes: 6c691b3e5099 ("jobs: Only clear gotsigchld when waiting...")

This change also incorporates other changes to bring us closer to upstream.
