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

Log Message:
ATF: Add new test race1 in t_ptrace_wait*

Reuse the attach1's test body for race1.

Add a new test race1:
  Assert that await_zombie() in attach1 always finds a single
  process and no other error is reported

race1 requires HAVE_PID in wait(2)-like function.

This test is executed in a loop for 5 seconds (16k iterations on Intel i7).
A buggy kernel was asserting an error within this timeframe almost always.

The bug in the kernel is now gone and this test is expected to pass
correctly.
