Title:
Add "sun4i-drm_dri.so" to libg1-mesa-dri and fix compilation on
riscv64

Status in mesa source package in Jammy:

Bug description:
[Impact]
lima driver is missing from riscv64, but in order to enable it we need
to disable anything that uses JIT on riscv64: swrast for vulkan, and
draw-use-llvm for gallium.
JIT for riscv64 is buggy and should be fixed in a future llvm release.
[Test case]
Check that sun4i-drm_dri.so is in libgl1-mesa-dri deb for riscv64, and
that it works.
[Where things could go wrong]
This is a new driver for the architecture, so there's little chance of
breakage.
--
"sun4i-drm_dri.so" is needed for some RISC-V platforms such as the
Allwinner D1. This file is missing from the riscv64 packages, but
present on others. This affects (at least) 20.04 and 22.04.
