NEWS: add a comment about udev's MemoryDenyWriteExecute= setting (#5414)

Browse Source 
Apparently if people are adventurous enought to run Go programs in udev
rules they might run into problems with MemoryDenyWriteExecute=.

I am pretty sure the best way out is for the toolchain generating
programs incompatible with W^X to be fixed, but this still deserves
documentation.

This was forgotten for the 232 release, hence add it now, retroactively.

See: #5400

CHANGES WITH 232:
* udev now runs with MemoryDenyWriteExecute=, RestrictRealtime= and
RestrictAddressFamilies= enabled. These sandboxing options should
generally be compatible with the various external udev call-out
binaries we are aware of, however there may be exceptions, in
particular when exotic languages for these call-outs are used. In
this case, consider turning off these settings locally.
* The new RemoveIPC= option can be used to remove IPC objects owned by
the user or group of a service when that service exits.
