Make background of CopyableLabel transparent

The flash animation to display a CopyableLabel has now a transparent
background.

In Gerrit the background of the CopyableLabel will now always have
the color that is defined as background color in the theme. Before
this change the CopyableLabel always had a white background which
looked bad if a non-white background color for Gerrit was configured.
