package/panel-mipi-dbi-firmware: replace host-python3 with BR2_PYTHON3_HOST_DEPENDENCY

The mipi-dbi-cmd script does not require a particular python3
version. Using BR2_PYTHON3_HOST_DEPENDENCY avoids the need to build
host-python3 if python3 is installed on the host, and nothing else in
the build depends on host-python3.
