s390/rethook: add local rethook header file
Compiling the kernel with CONFIG_KPROBES disabled, but CONFIG_RETHOOK
enabled, results in this sparse warning:
arch/s390/kernel/rethook.c:26:15: warning: no previous prototype for 'arch_rethook_trampoline_callback' [-Wmissing-prototypes]
26 | unsigned long arch_rethook_trampoline_callback(struct pt_regs *regs)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Add a local rethook header file similar to riscv to address this.
