package: fix 'local' site method for host packages

Using the 'local' site method works just fine for target
packages. However, for host packages, when HOST_<pkg>_SITE is
automatically defined by the package infrastructure to be equal to
<pkg>_SITE, when defining the <pkg>_OVERRIDE_SRCDIR, the $($(2)_SITE)
is empty, due to a missing additional dollar sign.

This patch ensures that the <pkg>_OVERRIDE_SRCDIR gets the correct
value, regardless of whether the HOST_<pkg>_SITE variable has been
defined by the package itself, or inferred by the package
infrastructure using the <pkg>_SITE value.
