[man-pages PATCH 1/5] s390_runtime_instr.2: note that runtime_instr.h is not a public header

[Eugene Syromyatnikov <evgsyr-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

For some reason, runtime_instr.h is inside arch/s390/include/asm/ and
not arch/s390/include/uapi/asm/, so it's not readily available to the
user space programs. Let's reflect it.

* man2/s390_runtime_instr.2 (.SH SYNOPSYS): Comment out the #include
<asm/runtime_instr.h> statement.
(.SH NOTES): Note the existence and presence of runtime_instr.h header
inside the Linux kernel source tree.
