Fix use-after-free on Windows in escript
Since commit 385b18de6fd72672ed7d6736b30f56d6691d4433, the emulator path was not
copied anymore before pushing it to the args vector (before it was done within
the `push_words` function. Since on Windows `free_env_val` is not a NOP as it is
on Unix systems, the string is freed and afterwards used, leading to strange
errors like this:
escript: Error executing 'àyI': 2
This is fixed by removing the `free_env_val` call.
