pkg-infra: add <pkg>-extract and <pkg>-patch targets to OVERRIDE support
The legal-info target (and possibly others as well) depends on
<pkg>-extract to make sure the license file is available. However,
when <PKG>_OVERRIDE_SRCDIR is active, the <pkg>-extract target
doesn't exist.
To solve this, we add <pkg>-extract which depends on <pkg>-rsync.
While we're at it, we do the same for <pkg>-patch. That avoids the
same problem in the future if something starts depending on
<pkg>-patch.
