Fix SiamMask breakage due to a bad OpenCV version check (#8945)

Due to a poorly-written version check
(<https://github.com/foolwood/SiamMask/blob/0eaac33050fdcda81c9a25aa307fffa74c182e36/tools/test.py#L285>)
SiamMask will not work with any version of OpenCV greater than 4.9.9.
Cap the version we install to work around it.

Also, switch to the headless version of OpenCV, so that we don't have to
install GUI packages.
