conformance-hip.yml: Add symlink to Mesa driver during set up

[daniellegillai]

Motivation

PR #482 fails the CI rocJPEG ctests (basic_test_rocjpeg_rgb and basic_test_rocjpeg_gray) because VA-API is unable to find the mesa driver at /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so.

Technical Details

Creates a symlink so that /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so points to the driver at /usr/lib/x86_64-linux-gnu/libgallium-*.so.

Original ctest error message:

16: InitVAAPI(drm_node) returned ROCJPEG_STATUS_NOT_INITIALIZED at

  /rocAL/rocAL/source/decoders/image/rocjpeg_decoder.cpp:68 

Creating the symlink eliminates this error.

Test Result

The rocJPEG ctests now pass when this is run on my own system.
