set: make set flags output parsable

This patch fixes two problems:

- the output of "nft list table ..." is not parsable if sets are included
  because the parser can't parse the flags.

- set flags can't be specified during set creation.

To fix this, the set output is changed to:

- not print each flag on a single line
- prefix the flags with "flags "
- only show the interval flag since all others are for internal use only

The parser is changed to parse the flags specified in a set declaration.
This allows to parse empty sets. The following patch will take care of
parsing sets that are already populated.
