mpers_test.sh: check proper handling of sized integer types
The commit v5.6~62 ("v4l2: always decode VIDIOC_*_EXT_CTRLS ioctl
commands") unraveled a possibility of buggy handling of sized integer
types in some libc implementations[1][2]. Add checks for these types
to mpers_test.sh to catch such issues early.

* mpers_test.sh: Add checks for (u)int{8,16,32,64}_t types.
Complements: v5.6~62 "v4l2: always decode VIDIOC_*_EXT_CTRLS ioctl commands"
