ptrace_test: Add more debug output on test failures
Mostly automatic, using
`CHILD_REQUIRE\(([^|&\n]*) ==` -> `CHILD_REQUIRE_EQ_INT($1,`
`ATF_REQUIRE\(([^|&\n]*) ==` -> `REQUIRE_EQ_INT($1,` followed by
git-clang-format -f and then manually checking ones that contain ||/&&.
Test Plan:
Still getting the same failure but now it prints
`psr.sr_error (0) == EBADF (9) not met` instead of just failing
without printing the values.
