[B.A.T.M.A.N.] musl build fixes

[Alex Suykov <alex.suykov@gmail.com>]

batctl-2014.4.0 fails to build with musl, mostly because of somewhat
weird netinet/*.h headers musl provides, but the problem turns out
to be easy to fix.

musl does not allow including netinet/* and linux/* headers together.
batctl includes netinet/if_ether.h indirectly via net/ethernet.h,
so netinet/if_ether.h must be used instead of linux/if_ether.h.

__be16 and __be32 are linux-specific typedefs for uint16_t and
uint32_t with __attribute__((bitwise)) that has no effect
outside of the kernel. Replacing them with uint16_t and uint32_t
removes dependency on linux/types.h.
