[PATCH nft] meta: skip -T for hour and date format

[PATCH nft] meta: skip -T for hour and date format

[Pablo Neira Ayuso]

If -T is used:

- meta hour displays the hours in seconds based on your
- meta time displays the UNIX time since 1970 in nanoseconds.

Better, skip -T for these two datatypes and use the formatted output
instead, ie.

- meta hour "00:00:20"
- meta time "1970-01-01 01:00:01"

Fixes: f8f32deda31d ("meta: Introduce new conditions 'time', 'day' and 'hour'")
