bug#18716: 24.3; dired-omit-extensions's default value omits COPYING.LIB

Why?  If your software uses the LGPL, surely the file that holds the
copying rules should be called "COPYING" or "LICENSE" but not some name
with a funny ".LESSER" extension (which luckily corresponds to no known
format yet).  IF you want a different name depending on which license is
in use, it seems that "GPL-LICENSE" and "LGPL-LICENSE" would be better
choices.  Of course, I'd also argue in favor of a proper extension
(e.g. ".txt") and against the use of allcaps.
