pseudo: Fix to work with glibc 2.38

This adds a horrible hack to get pseudo working with glibc 2.38. We can't
drop _GNU_SOURCE to something like _DEFAULT_SOURCE since we need the defines
the gnu options bring in. That leaves using internal glibc defines to disable
the c23 versions of strtol/fscanf and friends. Which would break pseudo
build with 2.38 from running on hosts with older glibc.

We'll probably need to come up with something better but this gets glibc 2.38
and working and avoids autobuilder failures.

+glibc 2.38 would include  __isoc23_strtol and similar symbols. This is trggerd by
+_GNU_SOURCE but we have to set that for other definitions. Therefore play with defines
+to turn this off within pseudo_wrappers.c. Elsewhere we can switch to _DEFAULT_SOURCE
