tests/gem_ctx_bad_exec: Consolidate to gem_ctx_exec

Move a really small test that invalid context is rejected under the
gem_ctx_exec umbrella.

v2:
 * And actually fix the test so it does what it claims. And add more
   variety in the invalid context id's it tests with. (Chris Wilson)

v3:
 * Rename the test as basic.
 * Limit to 32-bit. (Chris Wilson)
 * Add previously valid but closed context id to the test. (Chris Wilson)

v4:
 * Add more invalid values. (Chris Wilson)
