Martijn Dekker 064baa372e More misc. tweaks and cleanups 
Notable changes:

.github/workflows/ci.yml:
- Run 'bin/package test' on the github runner so we test iffe too.

src/cmd/ksh93/sh/subshell.c:
- sh_assignok was usually called like 'np = sh_assignok(np,0)'. But
  the function never changes np, it just returns the np value
  passed to it, so the assignment is pointless and that function
  can be changed to a void.

src/cmd/ksh93/sh/fault.c: sh_fault():
- Remove check for sh.subshell after sh_isstate(SH_INTERACTIVE). As
  of 48ba6964, it is never set in subshells.
