[PATCH i-g-t v2 5/8] tests/intel/kms_frontbuffer_tracking: use a bigger fbc status buffer

[Vinod Govindapillai <vinod.govindapillai@intel.com>]

As the FBC status now include plane specific FBC status as well, we
need a bigger buffer to capture the complete FBC status. Define the
buffer length in a single place and use it across places where the
test need to assess the FBC status
