[PATCH i-g-t v2] tests/intel/kms_fbcon_fbt: Use linear instead of x tiled

["Jouni Högander" <jouni.hogander@intel.com>]

PTL doesn't support x tiled format and older platforms (display version <
9) do not have FBC support for linear. There is no specific reason to use x
tiled format in this testcase: switch to linear format except on older
platforms.

v2: use x tiled for display version < 9
