Jens Petersen 87f872d02b ghc-deps.sh: also support ghc-pkg for ghc build before 7.6
Now test for "%buildroot%_bindir/ghc-pkg-$GHC_VER" and if it exists it means
we are doing a ghc build and then condition on GHC_VER to set GHC_PKG.
Otherwise just use %_bindir/ghc-pkg-$GHC_VER as usual.

There are 3 cases: 7.8, 7.6, and earlier.
