libbpf: Fix arm syscall regs spec in bpf_tracing.h
The syscall register definitions for ARM in bpf_tracing.h doesn't define
the fifth parameter for the syscalls. Because of this some KPROBES based
selftests fail to compile for ARM architecture.
Define the fifth parameter that is passed in the R5 register (uregs[4]).
