freedreno/ir3: move the libdrm dependency out of shared code
The only reason for this dependency was the fd_bo used for the uploaded
shader. But this isn't used by turnip. Now that we've unified the
cleanup path from gallium, it isn't hard to pull the fd_bo upload/free
parts into ir3_gallium.
This cleanup has the added benefit that the shader disk-cache will not
have to deal with it.
