Cygwin: ldd: Also look for not found DLLs when exit status is non-zero

If the process exited with e.g. STATUS_DLL_NOT_FOUND, also process the
file to look for not found DLLs.

(We currently only do this when a STATUS_DLL_NOT_FOUND exception occurs,
which I haven't managed to observe)

This still isn't 100% correct, as it only examines the specified file
for missing DLLs, not recursively on the DLLs it depends upon.
