[PATCH i-g-t 2/3] tests: Shut gcc up abput _Atomic(uint64_t) alignment

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

x86-32 gcc keeps complaining about some alignment ABI change:
"note: the alignment of ‘_Atomic long long unsigned int’ fields changed in GCC 11.1"

State the alignment explicitly to make gcc shut up.
