Subject: [PATCH] device-linux.c: IEEE 802.15.4 musl libc fix

The ARPHRD_IEEE802154 macro's definition and name have been recently
moved around from kernel header to glibc headers.  Include linux/if_arp.h
if available and then use either ARPHRD_IEEE802154_MONITOR or ARPHRD_IEEE802154_PHY,
whichever comes first.
