join: don't report disorder against an empty file
This allows one to use join as a field extractor like:
join -a1 -o 1.3,1.1 - /dev/null
* src/join.c (join): Don't flag unpairable lines when
one of the files is empty.
* tests/misc/join: Add a new test for empty input, and adjust
a previous test that was only checking against empty input.
* doc/coreutils.texi (join invocation): Document the change.
* NEWS: Likewise.
