Fix tests for glibc 2.39 (#14097)

2.39 has fixed inconsistent (mon_)grouping formats in localedata:

* https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;hb=refs/tags/glibc-2.39#l237
* https://sourceware.org/git/?p=glibc.git;a=blob;f=localedata/locales/en_AU;hb=refs/tags/glibc-2.39#l65

For en_AU locale now it returns array of 1 item instead of 2 for
grouping and mon_grouping.

Since this is upstream change depending on the system, this only syncs
tests for such case.
