[Intel-gfx] [PATCH i-g-t v2] igt_core: Skip sync when listing subtests

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

No need to sync filesystems when only listing subtest.

Extremely marginal benefit of avoid a short stall after make
followed by listing subtests.

v2: Move sync to common_init for consolidation and simplicity.
