Enable cargo-auditable-binary-cataloger for files/directories

[ariel-miculas]

Especially when scanning a single binary file, the cargo-auditable-binary-cataloger should run and report the rust binary's dependencies:

scan --select-catalogers rust <binary_file>

This is in line with other binary catalogers, such as the go-module-binary-cataloger.
