Christian Schwarz 90e0219b29 python tests: support overlayfs for NeonEnvBuilder.from_repo_dir (#6295) ...

Part of #5771
Extracted from https://github.com/neondatabase/neon/pull/6214

This PR makes the test suite sensitive to the new env var
`NEON_ENV_BUILDER_FROM_REPO_DIR_USE_OVERLAYFS`.
If it is set, `NeonEnvBuilder.from_repo_dir` uses overlayfs
to duplicate the the snapshot repo dir contents.

Since mounting requires root privileges, we use sudo to perform
the mounts. That, and macOS support, is also why copytree remains
the default.

If we ever run on a filesystem with copy reflink support, we should
consider that as an alternative.

This PR can be tried on a Linux machine on the
`test_backward_compatiblity` test, which uses `from_repo_dir`.
