[cogl] Fix building the conformance and unit tests on mingw32

    Fix building the conformance and unit tests on mingw32
    
    The unit tests were failing to build with mingw32 because the
    libtest-fixtures was being included both by libcogl and the
    test-conformance and test-unit executables. That meant that the
    symbols were defined twice and it wouldn't link.
    
    The rule which depends on test-unit being built needs to be called
    test-unit.exe on Windows so this patch fixes it to use the $(EXEEXT)
    variable to get the right name.
