avoid OPEN_MAX in SCM_MAX_FD

The OPEN_MAX constant is an arbitrary number with no useful relation to
anything.  Nothing should be using it.  SCM_MAX_FD is just an arbitrary
constant and it should be clear that its value is chosen in net/scm.h
and not actually derived from anything else meaningful in the system.
