[bug#60224] [PATCH 3/9] gnu: make-uboot-package: Simplify build.

[Maxim Cournoyer]

* gnu/packages/bootloaders.scm (make-u-boot-package) <same-arch?>: Rename
procedure to 'native-build?'.
[native-inputs]: Remove field.
[arguments]: Specify the #:target argument, when not natively building.
Adjust for the above renaming.
