[Buildroot] [git commit] utils/diffconfig: use python3 explicitly

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=50b8d6307f92c26c10b769b58eb867856c5ed78a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Python 2 is EOL sice 2020 [1], it's still available on distros, but may
not be installed by default (as being replaced by python3). A
compatibility symlink python -> python3 may not be installed either.

Convert the shebang line to the usual /usr/bin/env based line.
