This file is no longer needed.
https://github.com/openbmc/openbmc/commit/7fabe70c853a1840b4aa009c6d96059dee117b8a
added it.

https://gerrit.openbmc.org/c/openbmc/bmcweb/+/69228 enabled
redfish-new-powersubsystem-thermalsubsystem by default remove it here in
the bbappend to keep things cleaner. Since this is the only one in the
bbappend, just remove the whole file.

Tested: I tested having this line removed in the meta-ibm bbappend when
testing 69228.
