[Buildroot] [PATCH 4 of 4 v2 for 2014.08] manual-text: hide image representations

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

Images specified in the asciidoc sources (currently only the logo) are
displayed as the file name in the text version of the manual. This causes an
odd line to appear:
    logo.png

Avoid this by setting the image representation macros to {empty} in
manual-text.
