[PATCH 2/2] recognize and ignore commands used by wg-quick

[Michael Tokarev <mjt@tls.msk.ru>]

When reading the config file, recognize and ignore commands in the [Interface] section
which are used by wg-qukck. This way wg-quick config file can be read by wg too directly
so there's no need to filter it out by wg-quick and it's easy to reload configuration too.
