Define SCTL_MASK32 when COMPAT_FREEBSD32 is defined.

Description

Define SCTL_MASK32 when COMPAT_FREEBSD32 is defined.

Remove the list of architectures and depend on COMPAT_FREEBSD32 which is
defined (if relevent) in opt_global.h and thus defined everywhere in
the kernel.

This is a minor change in behavior in that 32-bit compat for sysctls now
depends on COMPAT_FREEBSD32 rather than on the potential for 32-bit
compat support. The prior arrangement may have been part of an attempt
to allow 32-bit compat to be loadable, but such attempts are doomed to
failure (due to the fact that ioctls have no meaning without the
associated file descriptor) without vastly more refactoring and some
sort of COMPAT_FREEBSD32_SUPPORT option.
