bpo-21131: Fix faulthandler.register(chain=True) stack (GH-15276)

faulthandler now allocates a dedicated stack of SIGSTKSZ*2 bytes,
instead of just SIGSTKSZ bytes. Calling the previous signal handler
in faulthandler signal handler uses more than SIGSTKSZ bytes of stack
memory on some platforms.
(cherry picked from commit ac827edc493d3ac3f5b9b0cc353df1d4b418a9aa)
