tests: fix issues on alpine linux

* tests/misc/seq-epipe.sh: Remove stale comment.
* tests/misc/sort-debug-warn.sh: musl doesn't indicate a set_locale()
failure with missing locales, so avoid a test portion in that case.
* tests/misc/wc-files0.sh: Avoid a bug on older ash implementations.
Addresses http://bugs.gnu.org/28054
