config_entries: fix possible segfault when duplicating entries When duplicating a configuration entry, we allocate a new entry but do not verify that we get a valid pointer back. As we're dereferencing the pointer afterwards, we might thus run into a segfault in out-of-memory situations. Extract a new function `git_config_entries_dup_entry` that handles the complete entry duplication. Fix the error by using `GIT_ERROR_CHECK_ALLOC`.
