[Crash-utility] [PATCH 1/1] Calculate offset to field 'init_uts_ns.name'

The offset has changed in linux-next (v5.9.0) from 4 to 0 because there is no more 'kref' member variable at the beginning of 'init_uts_ns'. The change was introduced with commit 9a56493f6942c0e2df1579986128721da96e00d8. To handle both cases correctly, calculate the offset at run time instead.
