bmp: ignore alpha in Decode when the alpha channel is not supported

When the alpha channel is not supported, the alpha component in the
original image should be ignored in the decoded image data (that is,
set to 0xFF in the decoded data).

testdata/yellow_rose-small.png has been modified to pass the test.
No new test is added because testdata/yellow_rose-small.bmp has
covered this case.

Fixes golang/go#54368.
