On LEDE 17.01.5 at least, `/sys/module/wireguard/version` doesn=E2=80=99t =
exist, I=E2=80=99m not sure if this is the same for the release =
candidates of OpenWrt 18.06.

Unfortunately `modinfo wireguard` doesn=E2=80=99t give any indication of =
the version either for me with LEDE 17.01.5:

# modinfo wireguard
module:		/lib/modules/4.4.140/wireguard.ko
alias:		net-pf-16-proto-16-family-wireguard
alias:		rtnl-link-wireguard
license:	GPL v2
depends:	udp_tunnel,ip6_udp_tunnel

If you have installed WireGuard from the LEDE/OpenWrt package =
repository, then `opkg info wireguard-tools` to check the tools, and =
`opkg info kmod-wireguard` to check the kernel module is one way to =
verify the version:

# opkg info wireguard-tools
Package: wireguard-tools
Version: 0.0.20180625-1
Depends: libc, libmnl, ip
Status: install ok installed
Section: net
...

# opkg info kmod-wireguard
Package: kmod-wireguard
Version: 4.4.140+0.0.20180519-1
Depends: kernel (=3D 4.4.140-1-78acdb0e5133ba67c91f7694e305d1e7), =
kmod-udptunnel6, kmod-udptunnel4
Status: install ok installed
...

Note that updates to the tools appear to be backported regularly to LEDE =
17.01, but the kernel module appears to be as of the version available =
at the time of the release (17.01.5 in my case), so it isn=E2=80=99t =
unusual for these versions to not match as is the case here with mine. =
I=E2=80=99m not sure if the next release of OpenWrt will do a similar =
thing. It=E2=80=99d be nice if the kernel module updates were backported =
too.
