cc-mode.texi: Work around makeinfo alignment bug. Fix problem with ss index

* doc/misc/cc-mode.texi (top level): Using txicommandconditionals to
differentiate between the C and perl versions of Texinfo, create an "ss
index" unless we are both using the C Texinfo and are building the .dvi output
format.
(Config Basics): Work around a perl Texinfo alignment bug by writing a
separate version of an item list structure for this version, simplifying it
considerably.
