[Piglit] [PATCH] framework: fix duplicated TEST_BIN_DIR for cygwin

[Brian Paul]

The GLSLParserTest and ShaderTest subclasses of the PiglitTest class
were prepending the TEST_BIN_DIR variable onto the executable name
(such as "glslparsertest" and "shader_runner").  But the PiglitTest
class itself also does that so we were prepending TEST_BIN_DIR twice.

With unix paths, os.path.join("/abs/path1", "/abs/path2") returns
"/abs/path2".

But with cygwin, os.path.join("C:\\abspath1", "C:\\abspath2") returns
"C:\\abspath1/C:\\abspath2" which clearly causes trouble.

The solution is to only prepend the TEST_BIN_DIR path in the PiglitTest
class.

This issue was only encountered when the PIGLIT_BUILD_DIR env var was set,
which I just recently tried for the first time.

v2: don't change GleanTest, it's a subclass of Test, not PiglitTest.
