The old code is correct only when stride = 2*width.

This is required as PIX_FMT_GRAY8 has been declared as a paletted
format in FFmpeg r22191, fix GRAY8 -> RGB conversion.

Make swscale-test only perform the test from the input to the output
format rather than perform all.

Also implement swscale-test-all.sh, for performing all the tests.

Improve flexibility of the swscale-test tool, this way is simpler to
perform only a subset of tests.
