podman: `--mount type=glob` does not preserve symlinks

Broken out of https://github.com/containers/podman/issues/20000:

Here’s an example.

I’m using this line in my module file to do the glob mount:

"type=glob,source=/usr/lib64/libcuda*,destination=/usr/lib64,ro",

Here are our target libraries on the host system:

stephey@perlmutter:login24:/usr/lib64> ls -la | grep libcuda
lrwxrwxrwx  1 root root        29 Mar 28 20:44 libcudadebugger.so.1 -> libcudadebugger.so.525.105.17
-rwxr-xr-x  1 root root  10490248 Mar 28 20:44 libcudadebugger.so.525.105.17
lrwxrwxrwx  1 root root        12 Mar 28 20:44 libcuda.so -> libcuda.so.1
lrwxrwxrwx  1 root root        21 Mar 28 20:44 libcuda.so.1 -> libcuda.so.525.105.17
-rwxr-xr-x  1 root root  29867944 Mar 28 20:44 libcuda.so.525.105.17
stephey@perlmutter:login24:/usr/lib64> 

Here are the mounted libraries inside the container running with my gpu module:

root@8dd9e54b936a:/usr/lib64# ls -la | grep libcuda
-rwxr-xr-x  1 nobody nogroup  29867944 Mar 29 03:44 libcuda.so
-rwxr-xr-x  1 nobody nogroup  29867944 Mar 29 03:44 libcuda.so.1
-rwxr-xr-x  1 nobody nogroup  29867944 Mar 29 03:44 libcuda.so.525.105.17
-rwxr-xr-x  1 nobody nogroup  10490248 Mar 29 03:44 libcudadebugger.so.1
-rwxr-xr-x  1 nobody nogroup  10490248 Mar 29 03:44 libcudadebugger.so.525.105.17
root@8dd9e54b936a:/usr/lib64# 

We’d like the existing symlinks to be preserved.
