[Buildroot] [git commit branch/next] package/panel-mipi-dbi-firmware: replace host-python3 with BR2_PYTHON3_HOST_DEPENDENCY

[Julien Olivain]

commit: https://git.buildroot.net/buildroot/commit/?id=84d03a38bf44bbb30b8fc876afa59b96e6965159
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

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.
