Update conda build meta to use older system libraries and C++.

From searching:

The correct fix is to rebuild your Anaconda package while telling the compiler to target an older version of glibc (specifically, the version on Rocky 8 or older). Rocky 8 uses glibc 2.28.

You do not need to install an older Linux distro to do this. You can use Conda's sysroot features during the build.

If you are building a custom recipe: Add the sysroot dependency to your meta.yaml file in the build section. This forces the compiler to use an older set of headers and libraries, ensuring compatibility with Rocky 8.

requirements:
build:
- {{ compiler('c') }}
- {{ compiler('cxx') }}
# Target CentOS 7 glibc (2.17) for maximum compatibility
# OR target Rocky 8 glibc (2.28) specifically
- sysroot_linux-64 2.17
