ci: Run meson dist

This requires to change permissions for the directory to avoid git error:

    fatal: detected dubious ownership in repository at '/__w/iputils/iputils'
    To add an exception for this directory, call:

	    git config --global --add safe.directory /__w/iputils/iputils
    Error: Process completed with exit code 128.

(Only an old git 1.8.3.1 from CentOS 7 does not require that.)
