[FIX] packaging: avoid traceback on virtual machine timeout
[FIX] packaging: avoid traceback on virtual machine timeout

When the virtual machine used to build MS Win package takes too much
time (to build or to test the build), a warning is logged and the VM is killed.

Before this commit, the PID of the process was passed as an argument to
the warning method, causing a traceback.
