all: use <net/*> headers instead of <linux/*> where possible

The musl libc headers redefine some of the structs in linux/if_arp.h and
linux/if_ether.h, leading to compilation errors. Fix those by using the
libc provided versions of these headers and provide compatibility
defines for those that aren't present in older glibc versions.
