Enable tests for boot2qt

Websocket tests for boot2qt were disabled with commit
1a75da8d

. The tests can
be enabled since qtdeclarative now fallbacks to software
renderer if OpenGL is not supported.

Qemu still has missing syscall support so some tests need
to be skipped if that condition is detected.
