scripts/oe-debuginfod: correct several issues

Particularly:
- nesting subprocess.run() inside subprocess.check_output() does not work at all.
How was this tested?
- -R and -U options can be combined; no need to separate the invocations based
on packaging format
- both exception handlers are unnecessary; we can simply print the hint if
invocation did not succeed
- to run debuginfod from its own sysroot, '-c addto_recipe_sysroot' for elfutils-native
must be executed
