tests: Adjust i18n.test to 'fr_FR.utf8' locale in glibc 2.27.

* test-suite/tests/i18n.test (french-number-string=?): New procedure.
("number->locale-string")["French"]("integer", "negative integer")
("fraction", "fraction, 1 digit"): Use it.
("format ~h")["French"]("12345.678"): Likewise.
("monetary-amount->locale-string")["French"]("integer", "fraction"):
Check for both SPACE and NO-BREAK SPACE.
