Make appending to the newest log file in the fs logging backend optional.
By default, if there is still free space in the latest log file,
the fs logging backend appends to it on startup. This is useful for saving
space and avoiding the removal of older log files, if the maximum number
of log files has been reached. The drawback of this behavior is,
that log files that got appended can not be decoded, if the firmware
has changed between startups, for instance by an update,
since the log_dictionary.json used for decoding has also changed.
Therefore, it may be desirable to deactivate appending to log files.

This configuration option gives the possibility to not enable
the fs backend on startup.
Backend can be enabled in runtime using log_backend_init and
log_backend_enable functions.
Implementation is based on log_backend_net.

This is mainly to reduce clutter in `subsys/logging`, but also to make
backend management slightly easier.
