libbpf: Clean up now not needed __PT_PARM{1-6}_SYSCALL_REG defaults 

Each architecture supports at least 6 syscall argument registers, so now
that specs for each architecture is defined in bpf_tracing.h, remove
unnecessary macro overrides, which previously were required to keep
existing BPF_KSYSCALL() uses compiling and working.
