Manpage for virgl_test_server itself is present in online Debian manpage https://manpages.debian.org/testing/virgl-server/virgl_test_server.29 (if you need to look for the manpage of that program itself and not for arguments for using angle), but the virgl_test_server_android script yeah it doesn't have help argument yet

Adding the help of virglrenderer doesn't make sense, because on Android many options like --use-glx doesn't work anymore. I'll add usage of --angle-gl, --angle-vulkan and --angle-vulkan-null.
