Fix false positive with usedforsecurity flag in hashlib.sha1 (python)

[resimon]

Hello together,

similar to #3077

I want to propose that usedforsecurity is also considered as false positive for hashlib.sha1 in the python rules

So that

# ruleid:insecure-hash-algorithm-sha1
hashlib.sha1(1)

# ok:insecure-hash-algorithm-sha1
hashlib.sha1(1,usedforsecurity=False)
