Fix x86compatjit and x86lb legs
Fix x86compatjit and x86lb legs

Change 7eacdd7 moved Exclude from runtest.cmd to build-test.cmd, which
broke the x86compatjit and x86lb legs in the lab. This change splits the
builds for these jobs into build.cmd skiptests and build-tests.cmd Exclude
<exclusion file> and removes the Exclude option from the runtest command.
