[PATCH 7/8] samples: rust_minimal: demonstrate early_param usage

[Matthew Wood <thepacketgeek@gmail.com>]

Add an early_param annotation to the test_str parameter in the
rust_minimal sample module, registering it as "testing_early_str="
on the kernel command line.

When the module is built-in, this allows the parameter to be set
directly on the boot command line without dotted module notation:

    testing_early_str=world
