- Remove unused sysvec variables from various syscalls.conf.
- Send the systrace_args files for all the compat ABIs to /dev/null for
now. Right now makesyscalls.sh generates a file with a hardcoded
function name, so it wouldn't work for any of the ABIs anyway. Probably
the function name should be configurable via a 'systracename' variable
and the functions should be stored in a function pointer in the sysvec
structure.

GC unused 'syshide' override to /dev/null. This was here to disable
the output of the namespc column. Its functionality was removed some time
ago, but the overrides and the namespc column remained.
