Build: upgrade pre-built libraries for Linux

Replace ../lib/linux_centos7_x86_64 with ../lib/linux_x86_64_glibc_228,
built with Rocky8 Linux, compatible with the VFX platform CY2023,
see: T99618.

- Update build-bot configuration.
- Remove unnecessary check for Blosc, this is part of OpenVDB lib now.
- Remove WITH_CXX11_ABI, always use new C++11 ABI now
- Replace centos7 by glibc_228 everywhere

Note that existing builds with cached paths pointing to
"../lib/linux_centos7_x86_64" will need to be updated.

Includes contributions by Brecht.
