mesh: Increase plink action frame AMPY buffer length for max GTK/IGTK

The previous calculation of the buffer length did not take into account
the possibility of 32-octet GTK and IGTK values and it was also missing
something to cover the 16 octet keys that are supported now. Other
buffer elements were likely sufficient to cover all these cases, but
anyway, it is better to allocate sufficient size specifically for AMPE
to avoid issues in the future.
