[ft transfer benchmark] Add nearup to PATH (#11395)

Description of the script I changed: #11391.

I need to add this to `$PATH`, otherwise job inside `cron` don't see
`nearup` and `cargo`. Probably it could be done in some more generic
way, but I think since we want MVP asap this is fine.

Also added some lines to enrich logs and make debugging easier.
