config.c: remove last remnant of GIT_TEST_GETTEXT_POISON

Remove a use of GIT_TEST_GETTEXT_POISON added in f276e2a (config:
improve error message for boolean config, 2021-02-11).

This was simultaneously in-flight with my d162b25 (tests: remove
support for GIT_TEST_GETTEXT_POISON, 2021-01-20) which removed the
rest of the GIT_TEST_GETTEXT_POISON code.
