Mitigate s3 consistency issues for test_scanners_fuzz

IMPALA-7804 tries to reduce the frequency of S3 inconsistency issues by:
a. reordering some operations to give more time to S3 to get consistent
b. by adding -f to -put calls, which removes checking whether there is already a file with given path, making the PUT the first operation

tests/test_scanners_fuzz.py does -copyFromLocal calls without -f and -d, which is probably the cause of some of the inconsistency issues
