[PATCH i-g-t] tests/intel/xe_exec_threads: ignore expected hang timeout

[himanshu.girotra@intel.com]

From: Himanshu Girotra <himanshu.girotra@intel.com>

The hang subtests hang a queue and reset to recover. Jobs that were
queued but never started are logged by the KMD at warn level as
"Check job timeout: ... not started".

This warn is expected, but CI flags warn-level dmesg lines and fails
the subtest even though it passes. Whitelist it for the hang subtests.

v2: Rework description and comment to be generic (Priyanka,Kamil)
