Support build-id generation from compressed ELF files (elfutils >= 0.175)
Use dwelf_elf_begin() for reading ELF files for build-id generation on
versions that have it to support compressed ELF files such as kernel
modules (RhBug:1650072,1650074). Note that debugedit still cannot handle
compressed files, this is only for build-id generation.
