Subject: [PATCH] haskell-lib: make sdistTarball and buildStrictly functions
 fuzzier to cope with Hydra builds

In Hydra CI environments, the version strings we get from Hydra don't
necessarily match those hard-coded into the Cabal files. To make those builds
succeed anyway, we have to apply some pattern matching.
