Make ipodpatcher compile on *BSD and recent Linux distributions - htole16/htole32 are standard BSD functions, and they now also appear in glibc 2.9 or later on Linux. As the functions are so simple, we just rename to avoid a clash instead of attempting to use the library versions on some platforms. Same as fix provided in FS#10428 by Alyssa Milburn.
