LU-13042 tests: give more time in sanity-selinux test_21b

In sanity-selinux test_21b, set sepol refresh time to 1000 seconds
instead of 10. This gives plenty of time for file/dir access tests,
and also cache drop, to complete. Then reset send_sepol to a smaller,
already expired value, to force sepol refresh.

Test-Parameters: trivial
Test-Parameters: clientselinux mdtcount=4 testlist=sanity-selinux envdefinitions=ONLY="21b"
