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.
