The random seed is the same across invocations

[certik]

import random

def test_seed():
    print(random.random())
    print(random.random())

test_seed()

This gives in LPython:

$ lpython c.py 
7.82636925942561089e-06
1.31537788143166245e-01
$ ./c.out

Compared to CPython:

The random number generator itself works well, but the seed is always the same. We need to initialize the seed using system clock at the beginning of the program.
