build_abi.sh: Ensure valid abigail installation
As of now, build_abi.sh (indirectly) relies on libabigail while creating
the abi dump. In case abigail is not installed or not in PATH, this
script will do all the (time consuming) kernel building before failing
at its most essential step. Avoid that by ensuring a valid abigail
before building the kernel.
