self tests: work around 'unset' spurious non-zero return value * tests/self-check-exit.tap ($init): Unset the possibly already unset variable `am_explicit_skips' when the `errexit' shell flag is not yet active, for the benefit of shell that return a non-zero status when unsetting an already-unset variable.
