syz-manager, pkg/cover: normalize signals between VM instances
Adjust signal creation in syz-executor so hash
is independent of module offsets. This allows
for canonicalization of the signal between VMs.
Added signals to canonicalization/decanonicalization
between instances.
Coverts serialized Signal values as they have already
been serialized in rpc.go. Added a function in signal.go
to update serial signal elements.
