image/gif: revert incorrect usage of clear
CL 570555 replaced a loop which added empty
color.RGBA elements with a call to clear.
color.Palette is a slice of interfaces, so using
clear results in a slice of nil elements, rather
than what we previously had which was empty
color.RGBA elements. This could cause a panic when
attempting to re-encode a GIF which had an
extended color palette because of the weird
transparency hack.
This was discovered by OSS-Fuzz. I've added a test
case using their reproducer in order to prevent
future regressions.
