In commit e3fe6f5 I manually renamed SYS_SYSCTL to SYS___SYSCTL so that
syscall_bsd.go would continue to build, despite a rename of __sysctl to
sysctl somewhere between these two XNU versions:
http://www.opensource.apple.com/source/xnu/xnu-2422.90.20/bsd/kern/syscalls.master
http://www.opensource.apple.com/source/xnu/xnu-2782.1.97/bsd/kern/syscalls.master
In this commit I add a workaround that doesn't require manual edits to
autogenerated output, so regenerating the output should now cause no
diffs.
