Heiko Carstens df2f815a7d s390/runtime instrumentation: provide uapi header file
The man page for the s390_runtime_instr() system call refers to a
header file that was never exported. Therefore it's time to finally
provide the header file, and move large parts of the runtime
instrumentation header file to a new uapi header file.
