Use NFT_LOGLEVEL_* definitions in UAPI.
Make an internal definition of NFT_OSF_F_VERSION, this was originally
defined in the UAPI header in the initial patch version, however, this
is not available anymore.
Add a bison rule to deal with the timeout case.
Otherwise, compilation breaks.
Fixes: d3869cae9d62 ("include: refresh nf_tables.h cached copy")
