std::fs::copy also copies the original file permissions. If the original library at lib_path was not writable, e.g. because it had its permission set to 0o555, the copy inherited the same permission causing later file manipulations, like patchelf --set-soname to fail.

Fixes #1287

1292: add_external_libs: ensure write permission on libraries r=messense a=vlaci

`std::fs::copy` also copies the original file permissions. If the original library at `lib_path` was not writable, e.g. because it had its permission set to 0o555, the copy inherited the same permission causing later file manipulations, like `patchelf --set-soname` to fail.
