logging: use LOGL_NOTICE when no loglevel is set
when the API user of libosmocores logging infrastructure does not set a
pre-defined logging level in struct log_info_cat, the result would be an
invalid logging level. In order to avoid problems with that and to spare
all the additional .loglevel = LOGL_NOTICE (API users are advised to use
LOGL_NOTICE as default) lines in the user code lets check the logging
level on startup and set LOGL_NOTICE if there is no logging level set.
