tests: also check -Wchar-subscripts
GCC's -Wchar-subscripts may report issues on platforms where char is
unsigned. Unfortunately the current CI does not reproduce the
problem. But that would allow contributors to report issues if the
warning appears somewhere.
See 139d0655947c87f90af08718618feaaca0e558d7.
Problem reported by Andy Fiddaman in:
https://lists.gnu.org/r/bug-bison/2019-12/msg00021.html
* configure.ac (warn_common): Add -Wchar-subscripts.
