NSProcessInfo kernel dependency

[James Knight]

NSProcessInfo seems to have a gratuitous dependance on the particular 
kernel version in use. In particular, in +load, it attempts to count 
the number of arguments from the file in /proc. However, some versions 
of the kernel null terminate the last argument, and some don't. 
Currently, gnustep handles this by using a configure check to determine 
which kind of kernel you're on. That is less than ideal situation, 
because 1) it is easy to do the check at runtime, and 2) people can and 
do use the same binaries on different kernels. 3) getting the argument 
count wrong causes a segfault.

This patch fixes the bug.

The CMDLINE_TERMINATED check in configure can also be removed.
