Update devel/elfutils to 0.172

- Sparc patch no longer applies cleanly and was dropped.
- Other patches updated to apply to 0.172.
- stable/10 and 11.0 lack needed ELF header types; and 10 is closed.  Skip
  building on these (PR).
- gnulib handling was reverted to pre-r454110 style to allow using pkg.
