tests: avoid test-hup hanging on AIX

test-hup hangs on AIX. Under ksh89 on AIX (the default shell),

echo Hello; while [ ! -s not-there ]; do true; done

produces no output while the loop executes. Replacing 'true' with 'sleep 0'
fixes, as does using a less broken shell. ksh93 is fine.

Update check-code.py to look for this, and make same change in test-serve.t.
In fact test-serve works fine, probably because of additional commands between
echo and the loop, but that's a subtlety not easy to test for.

Test hangup signal in the middle of transaction

  $ "$TESTDIR/hghave" serve fifo || exit 80
  $ hg init
  $ mkfifo p
  $ hg serve --stdio < p 1>out 2>&1 &
  $ P=$!

Do test while holding fifo open

  $ (
  > echo lock
  > echo addchangegroup
  > while [ ! -s .hg/store/journal ]; do sleep 0; done
  > kill -HUP $P
  > ) > p

  $ wait
  $ cat out
