ffi: fix incorrect cptr type tag implementation.

We can't use the eltype field of the type structure
to store the cptr tag symbol, because that is expected
to be a type object and not a symbol.

* ffi.c (struct txr_ffi_type): New member, tag.
(ffi_cptr_put, ffi_cptr_get, ffi_cptr_alloc): Refer to
tag rather than eltype.
(ffi_type_compile): Handle the compound cptr type
using the same code as the simple one in ffi_init_types: use
make_ffi_type_builtin rather than make_ffi_type_pointer.
Install the tag into the tag field. Also set up the forgotten
alloc and free routines.
(ffi_init_types): For cptr, explicitly initialize the tag
to nil. This is not necessary since the structure is calloced,
and we rely on that for nil all over the place, but here it
serves as a reminder that cptr has a tag.
