Subject: [PATCH] haskellPackages.mkDerivation: jailbreak any/all cabal files

Since Cabal only allows a single cabal file per directory, we can just
jailbreak *.cabal which works even if the user doesn't have set pname to
match the cabal file name (which they SHOULD do, though).

The only remaining reference to ${pname}.cabal in the revision handling
code is fine since we know the proper name of the cabal file from
Hackage in that case.
