In order to support more flexibility in Wireguard configuration, ungexp the
configuration fields directly instead of ungexp-splicing a sexp
calculator. This allows for the fields to take arbitrary gexps instead of only
strings which is particularly helpful for the Pre/Post Up/Down commands.
* gnu/services/vpn.scm (wireguard-configuration-file): Ungexp configuration
lists instead of ungexp-splicing the code surrounding them.
* doc/guix.texi (VPN Services)[wireguard]: Document it.
