MINOR: chunks: always initialize the output chunk in get_trash_chunk()
The get_trash_chunk() function is convenient and is sometimes used even
to get a temporary string. While the chunk is initialized, the string
may contain some random garbage that some code might retrieve if it uses
chunk->str directly without checking ->len. This is what happened in checks
after commit 25e2ab5 (MEDIUM: checks: centralize error reporting). It's not
easy to guess it at first so better pre-initialize the string with a zero.
