Remove OPEN_MAX

The OPEN_MAX macro in limits.h should not be there.  It claims to be the
limit on file descriptors in a process, but its value is wrong for that.
There is no constant value, but a variable resource limit (RLIMIT_NOFILE).
Nothing in the kernel uses OPEN_MAX except things that are wrong to do so.
I've submitted other patches to remove those uses.

The proper thing to do according to POSIX is not to define OPEN_MAX at all.
The sysconf (_SC_OPEN_MAX) implementation works by calling getrlimit.
