runtest: also update slow test timeout during `#if` clauses

For a `#if slow` test to be useful, we need the test timeout to be increased.
Without this, the slow section would likely be killed before it finish.

#require serve

  $ hg clone http://localhost:$HGPORT/ copy
  abort: * (glob)
  [255]

  $ test -d copy
  [1]

  $ "$PYTHON" "$TESTDIR/dumbhttp.py" -p $HGPORT --pid dumb.pid
  $ cat dumb.pid >> $DAEMON_PIDS
  $ hg clone http://localhost:$HGPORT/foo copy2
  abort: HTTP Error 404: * (glob)
