description:
sys/endian.h: fix typo in comment

Came here because lint complained about non-constant case expressions in
sys/arch/xen/xen/xennet_checksum.c, line 111 and 122, which read:

        case htons(ETHERTYPE_IP):
        case htons(ETHERTYPE_IPV6):

POSIX says:

        On some implementations, these functions are defined as macros.

NetBSD implements these functions as macros, and on little-endian platforms,
as well as in lint mode, the macros expand to function calls.
