gnu: elfutils: Update to 0.178series-2622

This introduces debuginfod support which requires a couple of new inputs.

* gnu/local.ml (dist_patch_DATA): Remove elfutils-tests-ptrace.patch.
  Add elfutils-0.178-tests-build-id.patch.
* gnu/packages/elf.scm (elfutils): Update to 0.178
  [native-inputs]: Add iproute and pkg-config.
  [inputs]: Add cpio, libarchive, libmicrohttpd, libcurl, rpm and sqlite.
  [synopsis]: Updated.
  [description]: Updated.
  [license]: List all licenses used.
* gnu/packages/patches/elfutils-tests-ptrace.patch: Removed. Fixed upstream.
* gnu/packages/patches/elfutils-0.178-tests-build-id.patch: New. Patches
  backported from upstream git.
