[meta-oe][PATCH] giflib: don't depend on libsm if x11 is unavailable

[Andreas Oberritter <obi@opendreambox.org>]

If DISTRO_FEATURES doesn't contain x11, libsm is not available.
As libsm is optional, the dependency is changed to be conditional.
There's no need to alter configure flags, because without x11,
libsm cannot be picked up accidentially. Because this just fixes
a missing dependency failure without x11, no PR bump is required
either.
