LU-11058 tests: stop running sanity test 77k

LU-11058 tests: stop running sanity test 77k

sanity test 77k is failing for a variety of Lustre
file system configurations. Stop running test 77k by
adding it to the ALWAYS_EXCEPT list.

When this issue is resolved, we need to resume running
sanity test 77k by removing it from the ALWAYS_EXCEPT list.
