MIPS: compat: Implement is_compat_task.
commit 4302e5d53b9166d45317e3ddf0a7a9dab3efd43b upstream.
This is a build fix required after "x86-64: seccomp: fix 32/64 syscall
hole" (commit 5b1017404aea6d2e552e991b3fd814d839e9cd67). MIPS doesn't
have the issue that was fixed for x86-64 by that patch.
This also doesn't solve the N32 issue which is that N32 seccomp processes
will be treated as non-compat processes thus only have access to N64
syscalls.
