Upgrade uffd-rs to 0.9.0, which comes with support for UFFDIO_CONTINUE,

by unconditionally grabbing the second part of the path of a modified
file in `run_all_tests()`, we ended up indexing out of bounds if a
modified file does not _have_ a second component in its path (e.g. if
the file is at the repository root, like `Cargo.lock`). Fix this by
checking for the length of x.parts first, and using python's
short-circuiting behavior of logical operators.
