tests/check/: but disable for now since it doesn't pass (something wrong with

Original commit message from CVS:
* tests/check/Makefile.am:
* tests/check/elements/.cvsignore:
* tests/check/elements/ffmpegcolorspace.c: (rgb_format_to_caps),
(create_rgb_conversions), (rgb_conversion_free),
(right_shift_colour), (fix_expected_colour), (check_rgb_buf),
(got_buf_cb), (GST_START_TEST), (ffmpegcolorspace_suite):
Add unit test for ffmpegcolorspace (RGB <=> RGB only so far),
but disable for now since it doesn't pass (something wrong with
RGBA somewhere).
