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.
