Remove separate *nix system build for Zend engine

Removed files used to provide building Zend engine separately using
Autoconf and Automake:
  cd Zend && ./buildconf && ./configure

Since Zend engine is tightly integrated in the PHP code itself and
current root configure.ac and acinclude provide this patch removes
these. Removed files also included several obsolete macros and
Automake dependency which is not used in main *nix PHP build system.
