images: Make locate(1) opt-in by default

Currently, the entry point of a Toolbox container runs updatedb(8) on
start-up, which can be very I/O intensive. This might be a hindrance
when troubleshooting performance problems on a host, or when
re-creating containers somewhat more frequently.

Users can install the mlocate RPM and restart their containers to
enable locate(1).

Only the images for currently maintained Fedoras (ie., 34, 35 and 36)
were updated.
