[PATCH 3/3] in scripts/export_report.pl use warn() to issue WARNING, so they go to stderr.

[Jim Cromie <jim.cromie@gmail.com>]

Also count CONFIG_MODVERSION warnings, and print an NB message at
start of SECTION 2 if any were issued.  Section 2 will be empty
if the build is lacking this CONFIG_ item, and user may have missed
the warnings, as they're off screen.
