xdr: header cleanup
#16047 notes that include/os/freebsd/spl/rpc/xdr.h carried an (apparently) incompatible license. While looking into it, it seems that this file is actually unnecessary these days - FreeBSD's kernel XDR has XDR_CONTROL, xdrmem_control and XDR_GET_BYTES_AVAIL, while userspace has XDR_CONTROL and xdrmem_control, and our implementation of XDR_GET_BYTES_AVAIL for libspl works nicely with it. So this removes that file outright. To keep the includes in nvpair.c tidy, I've made a few small adjustments to the Linux headers. By definition, rpc/types.h provides bool_t and is included before rpc/xdr.h, so I've created rpc/types.h for Linux. This isn't necessary for userspace; both FreeBSD native and tirpc on Linux already have these headers set up correctly.
