Use $USER instead of $LOGNAME for default friendly_name

Browse Source 
Using $USER in the friendly name will display which user minidlna is
running as on the clients, which can be helpful for detecting problems.
Using $LOGNAME on the other hand will display "root" as the username if
minidlna was started using the init script, regardless of which user
minidlna is currently running as.
