scripts/tracetool: silence SystemTap dtrace(1) long long warnings
SystemTap's dtrace(1) prints the following warning when it encounters
long long arguments:
Warning: /usr/bin/dtrace:trace/trace-dtrace-hw_virtio.dtrace:76: syntax error near:
probe vhost_vdpa_dev_start
Warning: Proceeding as if --no-pyparsing was given.
Use the uint64_t and int64_t types, respectively. This works with all
host CPU 32- and 64-bit data models (ILP32, LP64, and LLP64) that QEMU
supports.
