pcre2test: avoid using readline headers with libedit 

When asked to enable libedit in a system that ALSO has readline,
the headers of the former would be found and used by the earlier.

While that would mostly work, some functions will be missing
definitions (which is forbidden in C99), so instead abort the
configuration and let the user provide for them.
