systemd-resolved has a compatibility interface for use with resolvconf
scripts when resolvectl is called from a symlink from resolvconf.
However, when tearing down the interface, cmd_down calls del_if and then
unset_dns. In the case of systemd-resolved, deleting the interface also
removes the systemd-resolved entry and causes resolvconf -d to fail when
resolvconf really is a symlink to resolvectl. This causes `wg-quick
down` and 'wg-quick@.service' to exit with failure.
Instead we use the resolvconf '-f' flag to ignore non-existent
interfaces, supported by both openresolv and sd-resolved resolvconf.

`wg-quick strip` prints the config file to stdout after stripping it of
all wg-quick-specific options.
This enables tricks such as `wg addconf $DEV <(wg-quick strip $DEV)`.

This avoids another ip(8) invocation for little benefit.
Confirmed to work with iproute2 and busybox.

This knob might disappear at some point, and we don't want to encourage
its use, so it's not being documented, but this should help with
development of new implementations.

For properly configured Homebrew installations /usr/local/bin should be
before /bin, so this should still work. This allows the script to be
used in more than one setting.
