package/*/Config.in: fix help text check-package warnings

This commit fixes the warnings reported by check-package on the help
text of all package Config.in files, related to the formatting of the
help text: should start with a tab, then 2 spaces, then at most 62
characters.

The vast majority of warnings fixed were caused by too long lines. A
few warnings were related to spaces being used instead of a tab to
indent the help text.
