package/lib*: fix wrapping of Config.in help text

The check-package script when ran gives warnings on text wrapping
on all of these Config files.  This patch cleans up all warnings
related to the text wrapping for the Config files starting with
lib in the package directory.

The appropriate indentation is: <tab><2 spaces><62 chars>
See http://nightly.buildroot.org/#writing-rules-config-in

 for more
information.
