tee: generalize the --write-error option to --output-error

Adjust commit v8.23-140-gfdd6ebf to add the --output-error option
instead of --write-error, and treat open() errors like write() errors.

* doc/coreutils.texi (tee invocation): s/write-error/output-error/.
* src/tee.c (main): Exit on open() error if appropriate.
* tests/misc/tee.sh: Add a case to test open() errors.
* NEWS: Adjust for the more general output error behavior.

Suggested by Bernhard Voelker.
