      BUG#12561297:LIBMYSQLD/EXAMPLE/MYSQL_EMBEDDED IS ABORTING.
      
      Issue:
      ------
      New test case mysql_embedded.test was failing on pb2.
      
      Description:
      ------------
      To run this test case executable libmysqld/examples/mysql_embedded is required.
      But as per /libmysqld/examples/cmake_install.cmake this executable doesn't get
      copied to <install_dir> when mysql is installed at <install_dir>.That is
the
      reason it was passing in my local branch and failed on pb2 when pushed.
      
      Solution;
      ---------
      Added code in mysql-test-run.pl, which will try to see if this file exists.If
      It doesn't exist, test case will be skipped with a skip message. New code in
      mysql-test-run.pl looks only for directory libmysqld/examples/mysql_embedded
      because this is the only place where this file could/does exist.
     @ mysql-test/mysql-test-run.pl
        Added new variable for mysql_embedded executable.
     @ mysql-test/t/disabled.def
        enabled mysql_embedded.test which was disabled earlier.
     @ mysql-test/t/mysql_embedded.test
        Modified test case to first verify if mysql_embedded executable exists. If
        it does not, skip the test.

    modified:
      mysql-test/mysql-test-run.pl
      mysql-test/t/disabled.def
      mysql-test/t/mysql_embedded.test
