ns_dumpglyphs_stretch: remove erroneous ns_focus call
This fixes a problem in which minibuffer contents were no
longer drawn if the cursor was on a tab.

The ns_focus call was unmatched in some situations by a
call to ns_unfocus.  Presumably redrawing a tab lead to a specific
condition here.

The first reproducible test case was reported by Peter Collinson.
