copy any file from stage0/lib to stage0-sysroot/lib

With the LLVM 18 upgrade, the name of the LLVM library has been changed to something like
`libLLVM.so.18.1-rust-1.78.0-beta`, which `is_dylib` function cannot determine as it only
looks whether files are ending with ".so" or not.
This change resolves this problem by no longer doing that ".so" check, as we need all files
from the stage0/lib as they are all dependency of rustc anyway.
