tests/eventscripts: Add sanity check to esnure events.d/ can be found

If it can't, the installation is probably inconsistent, so a
(hopefully) helpful message is printed.  :-)

+That means that no eventscripts can be tested.
+
+One possible explanation:
+
+  You have CTDB installed via RPMs (or similar), so the regular
+  CTDB_BASE directory is in /etc/ctdb/
+
+  BUT
+
+  You have done a regular "configure" and "make install" so the tests
+  are installed under /usr/local/.
+
+If so, one possible hack to fix this is to create a symlink:
+
+  ln -s /etc/ctdb /usr/local/etc/ctdb
+
+This is nasty but it works...  :-)
