Possibly too lax lower bound on bytestring

[hvr]

With GHC 7.6.3 (which comes w/ bytestring-0.10.0.2, which the solver tries to preferably select if possible) I see the following compile-failure
(see also http://104.239.175.197:8080/package/bytestring-strict-builder#GHC-7.6/bytestring-strict-builder-0.4.2)

    Perhaps you need to add `bytestring' to the build-depends in your .cabal file.

@nikita-volkov I see a new version was uploaded which tightened the lower bound; I've also fixed up
https://hackage.haskell.org/package/bytestring-strict-builder-0.4.2/revisions/ accordingly.
