Update bash to 5.0.17 (Patch 17 for bash 5.0)

Patch 16 was for this problem:
  Bash waits too long to reap /dev/fd process substitutions used as redirections
  with loops and group commands, which can lead to file descriptor exhaustion.

Patch 17 (this one):
  There were cases where patch 16 reaped process substitution file descriptors
  (or FIFOs) and processes to early. This is a better fix for the problem that
  bash50-016 attempted to solve.
