[commit/Ada] improve message when cannot insert Ada exception catchpoint.

[Joel Brobecker <brobecker@adacore.com>]

Hello,

This tries to improve the error message pointed out by Pedro.
I think the problem was the generality of the error message, so
fixed thusly.

gdb/ChangeLog:

        * ada-lang.c (ada_exception_support_info_sniffer): Improve
        error message.

Tested on x86_64-linux, checked in.
