Before, it was looking for the executable with exactly

the name in $EDITOR, spaces and all, and failing to find it.

Now it splits it up by spaces before calling the shell.
Fixes issue: Issue 3652: rbt patch throws "OSError: [Errno 2] No such file or directory" if EDITOR contains flags

From the issue.
EDITOR="vim -X" python -c "from rbtools.utils.console import edit_text; edit_text('')"

Before, it crashed, now it does not.
