Makefile: fix version indicator

If we execute `wg --version` we get a different version string that does
not match with the version string in the openwrt makefile.

Current version string:
`wireguard-tools vreboot-13159-gac5caa2718 -https://git.zx2c4.com/wireguard-tools/`

Corrected versions string:
`wireguard-tools v1.0.20200319 -https://git.zx2c4.com/wireguard-tools/`
