[spice-common 1/2] Remove redundant #if defined(SW_CANVAS_CACHE) || defined(SW_CANVAS_IMAGE_CACHE)

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

SW_CANVAS_CACHE is always defined when building spice-gtk,
SW_CANVAS_IMAGE_CACHE is always defined when building spice-server, and
they are the only 2 users of spice-common. Moreover, build when none of
these is defined is broken.
