Fix string literal length for compressed_data_info

The function `compressed_data_info` returns a record containing `name`
but copies the data from string literal. Since `heap_form_tuple`
expects a `name` value as source as well, it will copy too much data
from the source, leading to ASAN complaining about copying outside the
allocated range of data.

The problem is fixed by using buffers of size `NAMEDATALEN` for each
source string, ensuring that each of the string literals has sufficient
data for being copied as names.
