vm/qemu: strip ssh warnings
...
This patch sets the ssh loglevel to error to avoid noisy warnings, specifically
known host errors like:
Warning: Permanently added '[localhost]:1569' (ECDSA) to the list of known hosts.
Previously this appeared at the top of every crash report.

fuzzer: warn about absent kcov/kmemleak files

Also make local mode more usable.

vm/adb: make more robust
...
Add timeout to adb invocations and do more reliable reboot.
Clean up temporary files from previous runs.
Also pass enabled syscalls via rpc, as adb barks at too long command line.
Abd is still unreliable, though. Devices hang.

vm: faster output oops grepping
...
Use manual parsing instead of a regexp.
Regexp takes ~220ms for typical output size. New code takes ~2ms.
Brings manager CPU consumption from ~250% down to ~25%.

First, "cut here" is not interesting as it always follows
by a more descriptive message.
Unreferenced object is interesting.
Also, strip \r at the end.

vm/qemu: fix output reading bug

If qemu boot retries several times due to busy tcp port,
it ends up with several output reading goroutines.

vm: improve VM interface

Current interface is suitable only for running syz-fuzzer.
Make the interface more generic (boot, copy file, run an arbitrary command).
This allows to build other tools on top of vm package
(e.g. reproducer creation).

If you set "leak":true in manager config, it will do leak checking.
It's quite slow, though. Also there seems to be false positives
