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

[onur-ozkan]

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.

Fixes #122913

Confirmed that the LLVM file is copied into stage0-sysroot and cargo +stage0 build works.

I thought I fixed is_dylib when I fixed the nix patching?

[Kobzol]

That might be an orthogonal issue, but I would personally prefer to copy everything anyway, we just want to duplicate the lib directory to build the stage0 sysroot, so it seems more forward compatible to copy everything.

Library name is libLLVM.so.18.1-rust-1.78.0-beta, is_lib doesn't do anything useful to detect it.

Lines 56 to 59 in 760e567

	/// Returns `true` if the file name given looks like a dynamic library.
	pub fn is_dylib(name: &str) -> bool {
	name.ends_with(".dylib") || name.ends_with(".so") || name.ends_with(".dll")
	}

[onur-ozkan]

We also have a linker script file that ends with .so which isn't a dynamic library anyway.

ah no, I created a competing implementation https://github.com/rust-lang/rust/pull/122911/files#diff-11a177c4925352bc8852241c59fd49c369df531495f11f81914eb6972783bb8aR747
