Set libc versioning to GLIBC 2.2.5 ot add support to inject custom headers to generated runtime-headers.h

[comm644]

Problem:

1. When we create commercial software we need build application for all Linux-based distros.
2. We can't build static binary because because some GLIBC features does not support it. (related to authorization, change permissions)

Solution.

1. Build KPHP runtime with using version headers https://github.com/wheybags/glibc_version_header
2. Provide CMake flags for including custom headers to build sequence and runtime-header.h

Current my way:

Fix functions version for runtime library:

Note: Option -include breaks compiler caching when KPHP build it.

Also: I rebuilt all dependencies with this headers: libh3, libsqlite, libcurl, libkphp-timelib

Note: patchelf utility does not work very good for fixing symbols version.
