bpf: Move btf_type_is_struct_ptr() under CONFIG_BPF_SYSCALL

Browse Source 
The static inline btf_type_is_struct_ptr() function calls
btf_type_skip_modifiers() which is guarded by CONFIG_BPF_SYSCALL.
btf_type_is_struct_ptr() is also only called by CONFIG_BPF_SYSCALL
ifdef code, so let's only expose btf_type_is_struct_ptr() if
CONFIG_BPF_SYSCALL is defined.
