Build script looking for libraries in the wrong folder on ARM64 Linux

When I try to build the project with the default config on ARM64 Linux (specifically Ubuntu 24.10), it seems like it fails to build because it's looking for libraries in the `x86_64-linux-gnu` folder rather than the `aarch64-linux-gnu` folder.
```
scons: *** [demo/addons/godot-git-plugin/linux/libgit_plugin.linux.editor.arm64.so] Implicit dependency `/usr/lib/x86_64-linux-gnu/libssl.a' not found, needed by target `demo/addons/godot-git-plugin/linux/libgit_plugin.linux.editor.arm64.so'.
```

I'm able to work around the issue by explicitly overriding the library locations for libssl and libcrypto (which also seems affected) like this:
```
scons linux_openssl_static_ssl=/usr/lib/aarch64-linux-gnu/libssl.a linux_openssl_static_crypto=/usr/lib/aarch64-linux-gnu/libcrypto.a
```
