[Buildroot] [PATCH] graph-depends.py: support python3

[Vivien Didelot <vivien.didelot@savoirfairelinux.com>]

Reviewed-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com>

But there's also support/scripts/graph-build-time and support/scripts/xorg-release.
There are some calls to the Python executable in docs/manual as well.
