Fix builds for the OSS-Fuzz project

Since 70b1777d8aef75da1b184fe8155dc818ce66628a was commited the OSS-Fuzz
build was broken because the `chunk_get_raw()` was not updated in the
`FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION`-enabled area.  Add the `size`
argument to the fuzzing version of the `chunk_get_raw()` function.
