graphics/giflib: Add patch to fix regression
There is a regression with the 5.1.2 update to giflib. This affects the
ability for applications to render gif images usually ocurring after the
first gif image is rendered. Upstream has been notified but has not yet
provided feedback.
giflib 5.1.2 was a security fix, so reverting is not reasonable.
"The removed check look redundant - I couldn't find a code path where
Private->RunningBits would exceed that limit after initialization.
(Currently Private->RunningBits is checked before it is initialized)."
