[PATCH i-g-t 10/17] tests: Add gem_ctx_param_basic

[Daniel Vetter <daniel.vetter@ffwll.ch>]

Boring ioctl validation. Luckily no gaps found while doing it.

v2: git add ftw!

v3: Fixes:

- args->size is an outparam for get, adjust test.
- Pick an invalid param, not an invalid ioctl number ... tsk.
