fix home buffer random banner choice 

Random banner choice was broken by the presence of the `img` directory.
Even if `random` was set instead of `random*` in .spacemacs file the
cate banner would still show.

This commit fixes this bug while simplifying the existing code by adding
a regexp filter to only choose "*.txt" files.
