Add fuzzing to zipfile and tarfile modules

[sethmlarson]

The zipfile and tarfile modules both are used to process potentially untrusted inputs from the internet, most relevantly through Python packaging. zipfile and tarfile have security-focused settings to allow unpacking archives into specific directories with the expectation that the contents only affect the directory being unpacked into and not other directories. This gives an easy target to evaluate, whether the filesystem beyond the target directory is modified.
