env_dup: Allocate memory from the correct memory pool
...
When the initial proxy task is duplicated into the first user task,
the environment exists in kernel memory and this must be copied to user
memory.
The memory allocated for the new task was allocated with the parent's
priority which is incorrect. Use the new task's priority instead.
Follow-up for: #5753

Fix the initial idle tasks environment
...
- User mode allocator was used for setting up the environment. This
works in flat mode and probably in protected mode as well, as there
is always a a single user allocator present
- This does not work in kernel mode, where each user task has its own
heap allocator. Also, when the idle tasks environment is being set,
no allocator is ready and the system crashes at once.
Fix this by using the group allocators instead:
- Idle task is a kernel task, so its group is privileged
- Add group_realloc
- Use the group_malloc/realloc functions instead of kumm_malloc

sched/env_dup.c: Fix an error in the duplication of the child tasks environment in the special case where the parent's environment was created, but then all of the variables were unset. In that case, there is still an allocation in place but the size of the allocation is zero. This case was not being handled correctly when a child task attempts to create its environment and inherit the zero-size partent environment. Noted by Anthony Merlino.
