[PATCH v2] wireguard-tools: drop the dependency on ip-{tiny,full}

[Rui Salvaterra]

BusyBox ip already provides the required functionality and is enabled by default
in OpenWrt. This patch drops the ip dependency and makes the BusyBox ip required
dependencies explicit, allowing for a significant image size reduction.

openwrt-ath79-generic-ubnt_nanostation-loco-m-squashfs-sysupgrade.bin size:
4588354 bytes (with ip-tiny)
4457282 bytes (with BusyBox ip)

v2: take more accurate size measurements, with the same GCC version. (I hadn't
noticed I had also bumped GCC from 9 to 10, which inlines more aggressively.)
