lxc: default log appender on stderr

The default appender for logs is currently the file one: this
make macros from log.h unusable as long as lxc_log_init() hasn't
been called. This prevents errors from even being printed on
stderr in lxc_caps_init() for example.

Let's make stderr the default appender.
