Use powershell for system-info CPU temp on WSL

Replace the query of CPU temp from the OpenHardwareMonitor's JSON served
via the network on the Windows host with a call to powershell to instead
read the WMI objects that OpenHardwareMonitor also emits. This is more
robust since powershell.exe is always available and does not require
Windows Defender firewall rules to allow connections from WSL2's VM to
the Windows host.
