The paths generated from calling bpf_d_path can have a " (deleted)" suffix when a file is removed from the system, this can mess with our files being reported, so some basic sanitization is added to these buffers.
A new test is added which builds and runs a small container with a Rust binary that deletes itself and accesses a monitored file. This will trigger an open event where the executable path retrieved by the `bpf_d_path` helper will add a " (deleted)" suffix, the test checks our code correctly strips this suffix.

The name is quite misleading, since no parsing is happening. How about sanitize_d_path?

Done. Also added a small paragraph here for files ending with (deleted) being an edge case that we don't cover.
Also add a small paragraph on files that end with the " (deleted)" suffix being an unaddressed edge case.

Testing Performed
Created a small Rust binary that will delete its own executable and then try to access a file provided as an argument, this can be run standalone for manual checking. A new integration test was added which builds a container with this binary and then runs it to check the
(deleted)suffix is properly stripped from the executable path.
