remove upper bounds of dependencies

[kakkun61]

I think that upper bounds of dependencies that are not released yet are not necessary. When some versions will get incompatible, then upper bounds may be added.

Current versions of packages that are removed by this PR:

• containers-0.6.5.1
• directory-1.2.7.0
• dlist-1.0
• filepath-1.4.2.1
• transformers-0.6.0.2
• transformers-compat-0.7.1
• semigroups-0.20
• HUnit-1.6.2.0
• test-framework-0.8.2.0
• test-framework-hunit-0.3.0.2
• test-framework-quickcheck2-0.3.0.5
