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

(From meta-ibm rev: 2790b22411920574b95111a44137be21e07a2e3a)
