chore: call cleanup on tmpfile and replace some io.ReadAlls with streams (#4629)
* fix(deb and snaps): prevent excess reads

Previously, Syft could allocate excess memory or tempfile space if there
were highly compressed objects in deb archives, or at paths where the
kernel changelog was expected by the snap cataloger. Use io.LimitReaders
for extracting parts of deb archives, and refactor the snap cataloger's
reading of the kernel changelog to use a streaming parsing, eliminating
the possibility of excess allocation.
