Bug #52149 - packaging differences in CMake build

Corrected some packaging bugs:
- install mysqlservices library
- install libmysqlclient_r.so.{16,16.0.0} as links
  to libmysqlclient.so
- install libmysqld-debug.a
- install my_safe_process, my_safe_kill and
  symlinks to mysql-test-run.pl (mtr, mysql-test-run)
  into correct place ${INSTALL_MYSQLTESTDIR}
