ref-manual: Review edits to several glossary variables.

I updated the following variables based on slight review changes
from Paul Eggleton:

 EXTRA_AUTORECONF - changed autoconf class to autotools
 KERNEL_IMAGE_MAXSIZE - Wording tweak
 AUTO_LIBNAME_PKGS - Wording tweak
 DEBIANNAME - [doc] string updated
 TCLIBCAPPEND - Second clarifying sentence in first para added
 PACKAGEGROUP_DISABLE_COMPLEMENTARY - [doc] string updated

(From yocto-docs rev: ff5c765ffab1cdf6fc8a007cebdf7114432f65ef)
