[committed] libphobos: Run unittest tests with dg-runtest.

[Iain Buclaw]

Hi,

This patches fixes the libphobos unittest testsuite to use `dg-runtest'
test driver rather than `dg-test', same as all other libphobos tests.
This prevents the tests from being ran multiple times when parallelized.

Set `libphobos_test_name' as well so that all tests get a unique name.

Regression tested on x86_64-linux-gnu/-m32, committed to mainline.

Regards,
Iain.
