add honggfuzz to autofz

[LSXCH]

Hi, Previously I tried to integrate honggfuzz into autofz. Referred to libfuzzer.py and wrote honggfuzz.py, the content is in the attachment.
honggfuzz.txt
And I tried to run honggfuzz with : autofz -o test -T 10m -f honggfuzz -t freetype2-2017
I found that honggfuzz ran successfully for a short period of time, produced around 950 seeds, and stopped producing new seeds.
I print the exec args :
['cgexec', '-g', 'cpu:/autofz/honggfuzz', '/fuzzer/honggfuzz/honggfuzz', '--rlimit_rss', '0', '-n', '1', '-z', '-i', '/seeds/fuzzer-test-suite/freetype2-2017', '-W', '/work/autofz/test/freetype2-2017/honggfuzz/crashes', '-o', '/work/autofz/test/freetype2-2017/honggfuzz/queue', '--', '/d/p/honggfuzz/fuzzer-test-suite/freetype2-2017/freetype2-2017', 'FILE']
and directly run it in comand line, it works fine.
Since I don't know honggfuzz particularly well, I'm wondering if there's something wrong with my honggfuzz.py writing?
