*: use latest release of staticcheck (#5057)

Browse source 
* *: use latest release of staticcheck

It also fixes a couple of things in the code flagged by the additional
checks.

Signed-off-by: Simon Pasquier <spasquie@redhat.com>

* Use official release of staticcheck

Also run 'go list' before staticcheck to avoid failures when downloading packages.
