[PATCH v2 2/2] ash: use JOBS as the compile time option it actually is

[Johannes Schindelin]

Using the constant in a regular `if (...)` pretends that this is
anything but a compile time option. Let's use `#if JOBS` instead,
making it *much* clearer what `JOBS` actually is.

Incidentally, this change fixes the build in setups where there are
no headers defining WIFSTOPPED and WSTOPSIG (where JOBS has to be
set to 0).

This partially reverts 4700fb5be (ash: make dowait() a bit more
readable. Logic is unchanged, 2015-10-09).
