[PATCH] abicompat: Port this to the multi-front-end architecture

[Dodji Seketeli <dodji@redhat.com>]

Hello,

I forgot to port abicompat to the multi-front-end architecture that
was put in place a while ago.  Namely, all the other tools now use
abigail::tools_utils::create_best_elf_based_reader to create the best
elf-based reader depending on if they are given DWARF, BTF or CTF
debug information.

This patch make abicompat use
abigail::tools_utils::create_best_elf_based_reader too.

	* tools/abicompat.cc (read_corpus): Use
	abigail::tools_utils::create_best_elf_based_reader to create the
	right reader depending on the debug information at hand.
