[pcie-check] Update underlying pcieutil command and add to sudoers file (#6682)

- Why I did it

As of Azure/sonic-utilities#1297, subcommands of pcieutil have changed to remove the redundant pcie- prefix. This PR adapts calling applications (pcie-check) to the new syntax.

Resolves #6676

- How I did it

Remove pcie- prefix from pcieutil subcommands in calling applications
Also add pcieutil * to sudoers file, as pcieutil requires elevated permissions
