[LNT] NFC: Fix order of globals and locals on exec

Summary:
Per https://docs.python.org/3/library/functions.html#exec, the globals
parameter comes before the locals one. Since `globals` and `locals`
refer to the same object for the call in question, we can remove
`locals`, which will cause the globals parameter to be used for both the
global and the local variables, thus keeping the same behavior.
