Change PHP 5.4 APC+OPCache memory comsumption formula

Both opcode cache and user cache should consume the same amout of memory
for both PHP 5.3 and PHP 5.4.

PHP 5.3 gears:
  small:  APC (opcode cache + user cache) => 64M
  medium: APC (opcode cache + user cache) => 128M
  large:  APC (opcode cache + user cache) => 256M

PHP 5.4 gears:
  small:  Zend OPCache (opcode cache) 32M  + APC (user cache) 32M  => 64M
  medium: Zend OPCache (opcode cache) 64M  + APC (user cache) 64M  => 128M
  large:  Zend OPCache (opcode cache) 128M + APC (user cache) 128M => 256M
