Eliminate recursive dependency on <sys/bswap.h> in MD <byte_swap.h>

On certain NetBSD archs, it isn't possible to include <sys/bswap.h>
directly without including <sys/endian.h> first. This has been
broken since at least before netbsd-10, but recent changes elsewhere
have made this problem more visible for some reason.

Fix this by not including <sys/types.h>, eliminating recursive
inclusion - <sys/types.h> includes <machine/endian.h>. It would
be nice to remove that line from types.h, since it's no longer
necessary, but currently the kernel assumes that <sys/endian.h> is
included from <sys/types.h> in various places (and possibly userspace
software does too).

For now we can take the less dangerous option by avoiding
including <sys/types.h> from these bswap headers. They don't need the
full header, and applications that assume transclusion aren't portable
anyway, since architectures like sparc64 don't include <sys/types.h>
via <sys/bswap.h>.

PR pkg/59839 palemoon, firefox, etc., don't build on arm64 any more
