cairo: Remove -Werror=array-bounds from compiler flags

cairo uses zero-length array tricks causing array-bounds warnings.

The warnings have been verifited to be harmless in 1.16.0; for extra
security, this should be re-checked after updating.

Removing -Werror=array-bounds here allows us to use -Werror=array-bounds
globally in OPTIMIZE_FOR=security mode.
