qa/standalone/scrub: extra delay in osd-scrub-test.sh

Modify TEST_just_deep_scrubs():
The test turns 'no-deep' off, and expects the scrub to be
concluded and reported within a short period. But the PG
already had a chance to try scrubbing (and fail due to
the 'no-deep'), and its 'not-before'
was pushed out by osd_scrub_retry_after_noscrub.

The fix is to reduce the value of osd_scrub_retry_after_noscrub
for this test, and to increase the timeout for the test itself.
