piglit: Add missing glslang dependencies

The vulkan configuration requires glslangValidator for build and
runtime.

Fixes configure error:
```
| CMake Error at CMakeLists.txt:191 (message):
|   glslangValidator required by vulkan tests not found
```

Fixes runtime error:
```
name: vulkan@shaders@fs-large-local-array
    result: fail
    returncode: 1
    out:
    err: glslangValidator: No such file or directory
glslangValidator failed
```
