MDEV-100 : innodb_plugin tests fail on Solaris.

The reason for the failure is that the loaded library has the same exported symbols
as the builtin one. So the plugin uses innodb functions e.g srv_boot from mysqld
rather than plugin's own. This causes the crash.

On Unix systems with gcc4 later this error was so far worked around using GCC's
visibility attribute. However, in our case, we're using gcc3.

See related MySQL bug http://bugs.mysql.com/bug.php?id=48524 and
http://bugs.mysql.com/bug.php?id=52263

The fix is to restrict symbol visibility in the plugin using version script 
(called map file on Solaris).
