build: disable -Wtype-limits, except in the test suite
The current implementation of lib/intprops.h results in "unsigned < 0"
comparisons, which triggers warnings. See
https://lists.gnu.org/archive/html/bug-bison/2019-10/msg00061.html
* configure.ac (warn_common): Disable -Wtype-limits.
(warn_tests): Restore it.
