Kees Cook 7d1254a148 nospec: Allow getting/setting on non-current task 
commit 7bbf1373e2 upstream

Adjust arch_prctl_get/set_spec_ctrl() to operate on tasks other than
current.

This is needed both for /proc/$pid/status queries and for seccomp (since
thread-syncing can trigger seccomp in non-current threads).
