Fix for the Cat in the Hat (test 24)

[Pavel Roskin]

Hello!

I believe, it's Ok to require that the commands in multiline
AC_TRY_COMMAND are separated by semicolons. If we agree on that, BUGS and
autoconf.texi will require some modifications.

The scope of this patch is only the testsuite. It fixed the test 24.

ChangeLog:
        * base.at (AC_TRY_*): Fix typos preventing the test from
        succeeding. Add a colon between "then" and "else". Separate
        commands inside AC_TRY_COMMAND with semicolons.
        From Nicolas Joly.
