infra/pkg-download: make the DOWNLOAD macro fully parameterised

Currently, the DOWNLOAD macro is context-dependent and expects
the PKG variable to be set to the current package.

This is not so nice.

Change the macro to expect the upper-case package name as a
parameter, rather than expect it from a variable.

Adapt the caller accordingly.
