wspoon: Fix max31785 hwmon startup
The max31785 hwmon instance fails to start after a systemd patch was
removed to handle special characters in the device paths. This uses
`systemd-escape` to escape and unescape the device path when the udev
rule triggers the max31785 hwmon startup script.
Resolves openbmc/openbmc#3443
