ctype(3): Clarify test program output.  Update compiler warning.

Should be a little easier to read.  The fact that isprint returns
_any_ nonzero value, not necessarily 1, isn't germane to the point
here, so showing it return 5 or 2 doesn't really help to illustrate
anything.

ctype(3): Fix versions and clarify what LIBC_ALLOWCTYPEABUSE does.

Both the extra diagnostics _and_ LIBC_ALLOWCTYPEABUSE are new in 11.

The extra diagnostics were not added in 10 (unless someone went ahead
and pulled them up while I wasn't looking!).
LIBC_ALLOWCTYPEABUSE doesn't guarantee that the program won't crash;
it just makes that depend on factors such as address space layout
randomization -- where the ctype tables appear in memory relative to
non-readable pages.

PR lib/58208: ctype(3) provides poor runtime feedback of abuse
