kernel/team: Allow retrieving more attributes

- Stored the additional start time of each team, expressed by
milliseconds since boot.
- Added more fields to the `team_info` structure. These field
include those provided by the `get_extended_team_info` syscall as
well as the newly introduced `start_time`.
- Extended the `_kern_get_team_info` system call to receive an
additional `size_t` argument. If this size is smaller than or
equal to the size of the old `team_info` structure, the newly
added attributes will not be retrieved.
