[Pkg-php-pecl] Bug#879475: php-igbinary: Please recompile to support php7.1

[anomie at users.sourceforge.net]

Package: php-igbinary
Version: 2.0.1-1

The package does not contain the shared library compiled for php 7.1,
only for php 7.0. Simply recompiling it locally with dpkg-buildpackage
produces a package that contains the necessary shared library and other
infrastructure, and seems to function correctly.
