utils: gen-version: Pass the meson source root to the gen-version.sh script
The gen-version.sh script expects to be called from a git repo, and sets its src_root variable accordingly. This may not always be the case if it is built from a tarball source - full support for which is in a future commit. The MESON_SOURCE_ROOT environnement variable does not get set when called from the meson vcs_tag() function, but does when called from the run_command() function, so that cannot be used either. Instead, explicitly pass the meson source root to the gen-version.sh script.
