LibCompress: Switch DeflateDecompressor
to a fallible constructor
We don't have anything fallible in there yet, but we will soon switch the seekback buffer to the new `CircularBuffer`, which has a fallible constructor. We have to do the same for the internal `GzipDecompressor::Member` class, as it needs to construct a `DeflateCompressor` from its received stream.
