src: Refactor fork-like ATG tests in t_ptrace_wait*

description:
Refactor fork-like ATG tests in t_ptrace_wait*
Add CPP syntax sugare to define each fork-like test within a single line
of code with less than 80 columns.
This is a preparation for new fork-like scenarios where we detach either
child and/or parent with PT_DETACH.
The code could be still reduced to smaller number of columns, instead of:
FORK_TEST(fork1, DSCR(fork,0,0,0,0,0), fork, F, F, F, F, F)
we could perhaps need 50% of it, as the data is duplicated.
On the other hand the line is already short and taking only a single line.
No functional change intended.
