Add new tests:
- waitpid_options
- waitid_options
- wait3_options
- wait4_options
- wait6_options
These tests are included in t_wait_noproc and t_wait_noproc_wnohang.
waitpid_options, wait3_options, wait4_options test combinations of options
of: bit for WALLSIG, WALTSIG, __WALL, __WCLONE and later a full combination
mask of WNOWAIT, WEXITED, WUNTRACED, WSTOPPED, WTRAPPED and WCONTINUED.
waitid and wait6 test full combination mask of WNOWAIT, WEXITED, WUNTRACED,
WSTOPPED, WTRAPPED and WCONTINUED -- excluded empty value and singular
WNOWAIT.
For compatibility reasons alter waitid and wait6 to test against options
WEXITED | WTRAPPED, as it's equivalent to waitpid, wait3, wait4.
The intention for these tests it to catch any possible issues with slighty
changed behavior of wait(2)-like functions in terms of valid options
values.
All tests pass successfully.
