Subject: scripts/namespace.pl: add source file location exceptions
From: Stephen Hemminger <shemminger@xxxxxxxxxx>
Teach namespace checker about some special case files where the source is
in unusual location. This fixes many of the source file not found errors
(more can be added), and also prevents false positives for functions not
being used.
