acfd9b4d56 Exclude fuzz corpora from tarball
* fuzz/Makefile.am: Do not include corpora in tarball
* fuzz/main.c: SKIP if corpora directory isn't found (make check)

The fuzz corpora are thousands of files, not needed for a standard build
from a distribution tarball. The reproducers of former issues are being
included for regression testing.
