stack list-dependencies --license is wrong for base

[ndmitchell]

Running stack list-dependencies --license I see:

base <unknown>
ghc-prim <unknown>
integer-gmp <unknown>
template-haskell <unknown>

However, running stack exec -- ghc-pkg describe base correctly states that base is BSD3. I guess it's because these packages are "built in" - if so, hardcoding knowledge for them might not be too bad.

I've investigated this a bit, and I think it is due to the line after this one. Not sure why wiredInPackages are removed from the source map, but I'm assuming there's a good reason for it.

I've modified the function to optionally include wired in packages, so now stack list-dependencies --license works as expected!
