Strip trailing empty lines when getting footers

Take the following git change description (Note: added ~ to avoid
having these lines be parsed as tags):

```
~Test
~
~Bug: something
~Change-Id: Something
```

Sometimes(?) `git log --pretty=format:%B%n <hash>..` returns:

```
~Test
~
~Bug: something
~Change-Id: Something

```

The trailing empty line trips split_footers() up, making it return
an empty footer.

This change removes trailing empty lines before processing them.
