vo_opengl: partially fix 0bgr format support

Fixes broken colors with --vf=format=0bgr (but only if deband is
disabled).

0bgr means the first byte is padding, while the following three bytes
are bgr. From the vo_opengl perspective, it has 4 physical components
with 3 logical components. copy_img_tex() simply copied 3 components
from the physical representation, which means the last component (r) was
sliced off.

Fix this by not using p->color_swizzle for packed formats, and instead
let packed formats set the per-plane swizzle in texplane.swizzle. The
latter applies the swizzle as part of operation in copy_img_tex(), which
essentially moves physical to logical representations.

Unfortunately, debanding (and thus with opengl-hq defaults) is still
broken.
