One of the backup schemes I use for finding kexts and kernels
on the local filesystem is to load a solitary binary when I don't
find any with a dSYM. This usually is a more confusing behavior
than helpful; people expect to get no binary loaded, or a binary
with debug information. This change stops loading kexts and
kernels that do not have an associated dSYM.
