WITHOUT_SERVER installs server-only files

When cmake is invoked with `-DWITHOUT_SERVER=1` it will install files that are not useful for a client installation. This includes binaries, scripts, man-pages and other files. Some seems to be test-suite related.

Installed files that are server-only:

• bin/mysql_convert_table_format
• bin/mysql_install_db
• bin/mysql_plugin
• bin/mysql_secure_installation
• bin/mysql_upgrade
• bin/mysqld_safe_helper
• bin/mysqlhotcopy
• bin/mysqltest
• man/man1/galera_new_cluster.1.gz
• man/man1/galera_recovery.1.gz
• man/man1/innochecksum.1.gz
• man/man1/mariadb-service-convert.1.gz
• man/man1/my_safe_process.1.gz
• man/man1/mysql.server.1.gz
• man/man1/mysql_client_test.1.gz
• man/man1/mysql_client_test_embedded.1.gz
• man/man1/mysql_convert_table_format.1.gz
• man/man1/mysql_fix_extensions.1.gz
• man/man1/mysql_install_db.1.gz
• man/man1/mysql_secure_installation.1.gz
• man/man1/mysqld_multi.1.gz
• man/man1/mysqld_safe.1.gz
• man/man1/mysqld_safe_helper.1.gz
• man/man1/mysqlhotcopy.1.gz
• man/man1/mysqltest.1.gz
• man/man1/mysqltest_embedded.1.gz
• man/man1/resolve_stack_dump.1.gz
• share/mysql/wsrep.cnf
• share/mysql/wsrep_notify
• local/share/mysql/binary-configure
• local/share/mysql/fill_help_tables.sql
• local/share/mysql/magic
• local/share/mysql/maria_add_gis_sp.sql
• local/share/mysql/maria_add_gis_sp_bootstrap.sql
• local/share/mysql/mysql-log-rotate
• local/share/mysql/mysql.server
• local/share/mysql/mysql_performance_tables.sql
• local/share/mysql/mysql_system_tables.sql
• local/share/mysql/mysql_system_tables_data.sql
• local/share/mysql/mysql_test_data_timezone.sql
• local/share/mysql/mysql_to_mariadb.sql
• local/share/mysql/mysqld_multi.server
• local/share/mysql/wsrep.cnf
• local/share/mysql/wsrep_notify

The cmake scripts need to be fixed to not install these files when WITHOUT_SERVER is defined.
