correct remote path handling

Hello, there

I bumped into a problem running src blocks using a remote (tramp) :dir. I've 
looked into it and found that the problem is that a temporary file is passed 
as a remote path to the remote process (temp file should be local to remote 
process).

I'm attaching fixes for python and shell src blocks. I didn't add any tests 
because that would require more than 15 LOC. I'm willing to add them, but 
directly to git repo.

I've signed the necessary papers from (to?) the FSF involving org mode, so I'm 
ready on my side to add tests and maybe add support for other tramp-related 
stuff.

Thanks
Felipe

    fix evaluate python code in remote directory

    Evaluating an "AST python code" should be local to the process /
    directory.

    `file-local-name` will do just this (strip the tramp prefix in path)
