Bash 4.4.12-r2 jobs hangs on arm (alpine 3.7)

Bash jobs are hanging with bash 4.4.12-r2 (from alpine 3.7) when running on armv7l :

sleep 10 & wait; echo "done waiting"

bash-4.4# sleep 10 & wait; echo "done waiting"
[1] 15
[1]+  Done                    sleep 10

echo is not executed and bash never give the hand back.

bash 4.3.48-r1 on alpine 3.6:

bash-4.3# sleep 10 & wait; echo "done waiting"
[1] 14
[1]+  Done                    sleep 10
done waiting
bash-4.3#

sh on alpine 3.6 or 3.7:

/ # sleep 10 & wait; echo "done waiting"
done waiting
[1]+  Done                       sleep 10
/ #

This was tested on a Raspberry Pi 3 and Scaleway C1 instance.

main/bash: fix jobs again

previous fix didnt solve the problem for 32 bit architectures.

We fix it by capping childmax to 8192.
