sysvipc: Fix SEM_STAT_ANY kernel argument pass [BZ #26637]
Handle SEM_STAT_ANY the same way as SEM_STAT so that the buffer argument of SEM_STAT_ANY is properly passed to the kernel and back. The regression testcase checks for Linux specifix SysV ipc message control extension. For IPC_INFO/SEM_INFO it tries to match the values against the tunable /proc values and for SEM_STAT/SEM_STAT_ANY it check if the create message queue is within the global list returned by the kernel. Checked on x86_64-linux-gnu and on i686-linux-gnu (Linux v5.4 and on Linux v4.15). Co-authored-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
