[Libguestfs] [PATCH 2/2] ruby: tests: convert from Test::Unit to MiniTest (RHBZ#1090407)

[Pino Toscano]

Convert the tests to the MiniTest test framework, but keeping the usage
of the old Test::Unit as fallback in case MiniTest is not available.
In the latter case, use a bit of "glue" to make the old API look like
the new API, so we can just rely on the newer MiniTest API.

(This is the same change as 2f5e9066db817f75b245f256abc0c64dd1ae54eb
in libguestfs.)
