UAPI: x86: Fix insn_sanity build failure after UAPI split

Fix a build failure in the x86 insn_sanity program after the UAPI split.  The
problem is that insn_sanity.c #includes arch/x86/lib/insn.c - which uses the
kernel string header.  This leads to conflicts for various definitions against
the /usr/include/ headers.

linux/string.h can be replaced with the normal userspace string.h if __KERNEL__
is not specified.
