rust-config: fix fallback to default not parsing the default value

When a config item's default is a string, it sometimes needs to be parsed
into another type, like in the case of `cmdserver.max-log-size`, that returns
a number of bytes from a human-readable amount like `25MB`.

The logic for the fix is explained inline.

    cc::Build::new()

        .file("src/sighandlers.c")
        .compile("procutil");
}
