mysql's idea of a suitable place to install the regression tests is
/usr/mysql-test.  To relocate this to a reasonably FHS-compliant place
like /usr/share/mysql-test, we have to hack up the paths in install_test_db.

 With no test cases named on the command line, mysql-test-run falls back
 to the normal "non-extern" behavior. The reason for this is that some
