wireguard: netlink: use WG_KEY_LEN in policies
When converting the netlink policies to YNL, the constants used
in the policy have to be visible to userspace.
As NOISE_*_KEY_LEN isn't visible to userspace, change the policy
to use WG_KEY_LEN, as also documented in the UAPI header:
$ grep WG_KEY_LEN include/uapi/linux/wireguard.h
* WGDEVICE_A_PRIVATE_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
* WGDEVICE_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
* WGPEER_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
* WGPEER_A_PRESHARED_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
[...]
Add a couple of BUILD_BUG_ON() to ensure that they stay in sync.
No behavioural changes intended.
