fix: retry blockdevice open in the installer

Browse Source 
We had these retries in other places, but not here.

This seems to happen more frequently with Linux 6.6 update, the tl;dr is
same: `udevd` tries to rescan the partition table at the wrong moment,
preventing Talos installer to open the partition which was just created.

It's a race, so workaround it by retrying the call.
