Module Name:    src
Committed By:   kamil
Date:           Fri Feb  8 03:08:00 UTC 2019

Modified Files:
        src/tests/lib/libc/sys: t_ptrace_wait.c

Log Message:
Refactor kill* test in t_ptrace_wait*

Drop original scenario of kill1 (PT_CONTINUE(SIGKILL)) as it duplicates
traceme_sendsignal_simple1.

New kill tests:
 - kill1: ptrace(PT_KILL) (previously kill2)
 - kill2: kill(SIGKILL)
 - kill3: killpg(SIGKILL)

All kill* tests share the same function body.

All tests pass.
