If the TurboJPEG instance passed to tjDecodeYUV[Planes]() was previously
used to decompress a progressive JPEG image, then we need to disable the
progressive decompression parameters in the underlying libjpeg instance
before calling jinit_master_decompress().

This commit also modifies the build system so that the "tjtest" target
will test for this issue, and it corrects a previous oversight in the
build system whereby tjbenchtest did not test progressive
compression/decompression unless WITH_JAVA was true.
