    opcache: Remove unused sys/ipc.h include from ZendAccelerator.c (#20662)

    As far as I can tell that's been there since the initial open source
    release (commit 528006a). The header defines ftok() and a handful of
    IPC_* constants, none of which are used here.

    System V IPC is increasingly being replaced by POSIX IPC and may
    therefore not be implemented on new and/or hobbyist operating systems
    such as SerenityOS[1]. In the past that wasn't an issue as the OPCache
    could be disabled, which is no longer possible as of PHP 8.5[2].

    I was able to build with the include patched out, but we would prefer
    this to be addressed upstream.
