Subject: [PATCH 10/40] tools include uapi: Grab a copy of linux/sched.h

From: Arnaldo Carvalho de Melo <acme@...hat.com>

So that we make sure we have recent enough defines for things
such as 'perf trace' system call argument beautifiers.

For instance, the 'clone' syscall argument 'flag' needs to use
CLONE_NEWCGROUP, and that is not available in RHEL7.
