[ticket/12582] Strip away copyrighted ICC profile

This images embed a non free ICC profile that doesn’t allow
modification:

http://web.archive.org/web/20020603153925/srgb.com/usingsrgb.html

Please use the proposed version stripping away this copyrighted binary
profile, probably embedded by an image software at one time:

	exiftool -icc_profile"-<=" phpBB/adm/images/phpbb_logo.png

I’ve checked the resulting image and trust it is identical to the
original.
