Chris Down 5663ddaed7 properties: Skip found set building for nominal case
bus_message_print_all_properties() inserts every name it walks into the
found-properties set, but the set is only used to report missing requested
properties at debug level.

Request the set from systemctl only when properties were specified and debug
logging is enabled, avoiding the unnecessary work in normal operation.

In my tests with `systemctl show` over 160 units this brings the
instructions retired from 1167.8M down to 992.6M, a reduction of 15.0%.
The output is unchanged.
