Update to tasty-hunit-0.10.0.3

The only point of this release is to introduce compatibility with GHCs
back to 7.0 (see https://github.com/feuerbach/tasty/pull/287).

Note, however, that these changes are not merged to the master branch,
and the future releases will only support the GHC/base versions from
the last 5 years, as per our usual policy. To test with even older
GHCs, you'll have to use this particular version of tasty-hunit (or
have the constraint solver pick it for you when testing with older
GHCs).

The source of this release is in the support-old-ghcs branch of the
tasty repository.
