kernel-devsrc: fix scripts prepare for powerpc

5.13 introduces some new tweaks required to get on target scripts
and prepare working for powerpc:

  - 'nm' is detected as 'nm --synthetic', so we adjust our replacement
  - more vdso is required on target, so we copy those files (like arm64
    does)
  - grep is required during processing, so we add it to the redpends
