migrate to golang.zx2c4.com/wireguard/wgctrl (#239)
* migrate to golang.zx2c4.com/wireguard/wgctrl

This commit introduces the usage of wgctrl.
It avoids the usage of exec calls of the wg command
and parsing the output of `wg show`.

* vendor wgctrl

* apply suggestions from code review

Remove wireguard.Enpoint struct and use net.UDPAddr for the resolved
endpoint and addr string (dnsanme:port) if a DN was supplied.

* pkg/*: use wireguard.Enpoint

This commit introduces the wireguard.Enpoint struct.
It encapsulates a DN name with port and a net.UPDAddr.
The fields are private and only accessible over exported Methods
to avoid accidental modification.

Also iptables.GetProtocol is improved to avoid ipv4 rules being applied
by `ip6tables`.

Implement an Equal func for Enpoint and use it instead of comparing
strings.

Package `netlink` provides low-level access to Linux netlink sockets.
MIT Licensed.

## Stability
See the [CHANGELOG](./CHANGELOG.md) file for a description of changes between
releases.
This package has a stable v1 API and any future breaking changes will prompt
the release of a new major version. Features and bug fixes will continue to
occur in the v1.x.x series.
In order to reduce the maintenance burden, this package is only supported on
Go 1.12+. Older versions of Go lack critical features and APIs which are
necessary for this package to function correctly.
**If you depend on this package in your applications, please use Go modules.**
## Design
A [number of netlink packages](https://godoc.org/?q=netlink) are already
available for Go, but I wasn't able to find one that aligned with what
I wanted in a netlink package:
- Straightforward, idiomatic API
- Well tested
- Well documented
- Doesn't use package/global variables or state
- Doesn't necessarily need root to work
My goal for this package is to use it as a building block for the creation
of other netlink family packages.
## Ecosystem
Over time, an ecosystem of Go packages has developed around package `netlink`.
Many of these packages provide building blocks for further interactions with
various netlink families, such as `NETLINK_GENERIC` or `NETLINK_ROUTE`.
To have your package included in this diagram, please send a pull request!
