Fix a potential file leak

Previously, if a write or sync error occurred, we would not have called
Close(). This commit refactors ReplaceFile() so that we are sure to call
Close(), and also attempts to delete the temporary file if errors occur.

See: https://github.com/kubernetes/kubernetes/pull/52119#discussion_r137916659
Fixes: #53060
