Properly determine if in locale for NV stringification

Commit 68e8f474bc686a86c064b695b9c7400313d7af65 used the wrong macro to
determine if the operation is within the scope of 'use locale'.  It also
has to operate under 'use locale 'not_characters'.

Tests for this are coming in the patch for [perl #118197].
