Parallel eval all result in the same processing #370

Describe the bug?

erg -c "print! 1" & erg -c "print! 2"

the result is

1
1

As a workaround, the problem is resolved by adding a hash value to the dumped pyc filename.

In case of -c option, the name of the dumped pyc file will be stdin.pyc. Since the hash value of the same string will still be the same, it is necessary to add a random suffix to the filename.
