[FIX] Reset extended NMT commands feature flag

* The extended NMT commands are only implemented for the sending MN
  direction. It indicates if a POWERLINK node is able to handle extended
  commands.
  -> As a result this feature flag needs to be set when it is implemented
     for CNs.

[FIX] Resolve hostname issue

* Correct name of the hostname object to fit to the specification
* Add one byte to the length of the hostname object to fix a problem
  when the object is written with the maximum length.
  -> This is a quick fix for this version! The final solution would
     need several changes in the EplObd module.
