Log Message: ----------- linux: remove sudo modprobe fallback from metal_linux_probe_driver

A library must not attempt to escalate its own privileges. The sudo modprobe fallback was incorrect for three reasons:

1. A library silently attempting privilege escalation on behalf of its caller is unexpected behavior and a security concern.

2. If modprobe failed due to missing CAP_SYS_MODULE, sudo will also fail unless passwordless sudo is explicitly configured in sudoers making the fallback redundant in practice.

3. On embedded and production Linux systems, sudo is often not installed, causing system() to fail silently or hang waiting for a password prompt.

If the driver is not found after modprobe, return -ENODEV and let the caller handle it.

Log Message: ----------- ci: load UIO kernel modules before running nonreg tests

The nr_tests job was relying on libmetal's internal sudo modprobe fallback in metal_linux_probe_driver() to load UIO modules at runtime. Now that the sudo escalation has been removed from the library, the CI environment must explicitly load the required modules before invoking the test suite.

Add a "sudo modprobe" step for uio, uio_pdrv_genirq, and uio_dmem_genirq prior to make test. Module loading with sudo privileges is the responsibility of the environment, not the library.
