Run run-checker with GOST test switched on

[mattcaswell]

Now that openssl/openssl#6650 has been merged we have a test capable of testing GOST ciphersuites if a GOST engine in present. The test requires that the environment variable OPENSSL_GOST_ENGINE_SO is set to point at gost.so. We should set up run-checker so that this is configured.

Uhmmmmm... I should have looked more closely at openssl/openssl#6650 when I had the chance.
Is there a reason the test wasn't implemented as an external alongside the bunch of 95 series tests we already have? Building the GOST engine automatically as part of the test should be quite easy, as far as I can tell.

Well, I didn't really view it as an external test. This is not about running tests provided by others as part of our test suite. This is running a test that we have written to test functionality in libssl. It's more along the lines of an external dependency (e.g. such as libz) which you need to have present in order to activate certain functions.

Since GOST is on by default this test will be run every time if the GOST engine is available. I'm not sure we necessarily want to build the engine every time we do a build. I more envisaged that it would be present on the run-checker box in compiled form that we could update from time to time.

Yeahok... I can see the benefit with that.
