Can't build test suite with ghc 8.4 due to bytestring-trie

[Dan Burton]

Adding weigh to skipped-tests on Stackage, due to this build failure with bytestring-trie. I can't find anywhere to report it so here's the error in case anyone knows how to pass it along to the right person.

[4 of 6] Compiling Data.Trie.Internal ( src/Data/Trie/Internal.hs, .stack-work/dist/x86_64-osx/Cabal-2.2.0.0/build/Data/Trie/Internal.o )

I can just remove that, it's more of a demo than a real test.

The weigh-maps test-suite build and run just right, now (using stack build weigh:weigh-maps --flag weigh:weigh-maps)
