If the "trace" PACKAGECONFIG is removed to disable cairo-trace (the
only part of the code licensed as GPL-3.0), we can adapt the licenses
for cairo-dbg and cairo-src so that they do not include "GPLv3+" and
thus they can be used also when, e.g., GPL-3.0 is blacklisted in
INCOMPATIBLE_LICENSE.

PATCHv3: Split in two patches, one that adds the "trace" PACKAGECONFIG,
and one that adapts the licenses for cairo-dbg and cairo-src if "trace"
is disabled.
