community/gitea: config log files are wrong and uncontrolable

gite default setting are not well managed cos log file are already assumed but not managed so sometimes that log file are not created or do not append nothing

take in consideration that gitea in alpine are started from the init script and cos settings are not tuned for alpine linux rare behaviour happened

suggestions:

1. patch the gitea sources to defaults to "file" event "console"
2. change in the ini file the log section to:

[log]
ROOT_PATH            = /var/log/gitea
MODE                 = file
MACARON              = file
ROUTER               = file
ACCESS               = file

this is important for servers, dockers and containers.. cos that process if are started does not log anything in some cases..

NOTE and take care of closing the log file; check #12461 (closed)
