Haiku-related ulimit overhaul:

Browse Source 
• print ulimit -a with the flag, like most other shells do
• move ulimit-1 regression test to ulimit-2 and exclude on Haiku:
  it can only set the -n and -V limits AFAICT
• document that some OSes (here: Haiku) can only set the soft limits
  (so “ulimit -nS 1024” is okay but -S is required)
• check “ulimit -c 0”, which dot.mkshrc uses, everywhere
  (if it errors out, hack around it or stub it out with MKSH_NO_LIMITS)
