Module Name: src
Committed By: kamil

Modified Files:
src/tests/kernel: t_ptrace.c
Log Message:
Add FORKEE_ASSERTX()/FORKEE_ASSERT() for forkee; simplify code
A child process cannot call atf functions and expect them to magically
work like in the parent.
The printf(3) messaging from a child will not work out of the box as well
without estabilishing a communication protocol with its parent. To not
overcomplicate the tests - do not log from a child and use err(3)/errx(3)
wrapped with FORKEE_ASSERT()/FORKEE_ASSERTX() as that is guaranteed to work.
Simplify and cleanup code of the tests.
