[PATCH v4] man/man5/gai.conf: Document glibc label additions

[dg]

From: "Dr. David Alan Gilbert" <dave@treblig.org>

Glibc includes some extra entries in its default label table
as listed in the gai.conf it distributes:
   https://sourceware.org/git/?p=glibc.git;a=blob;f=posix/gai.conf

Update the EXAMPLES to include the spec default and the version glibc
actually uses.

I changed the line breaks as

	+Glibc includes some extra rules in the label table
	+for site-local addresses, ULA, and Teredo tunnels.
