boards/common/arduino-atmega: Refactoring

Browse Source 
- including `avrdude.mk` and `serial.mk` is no longer needed
- the avrdude flag -F is dropped
    - This allows flashing a board having an MCU different to the one
      RIOT was compiled for
    - It is better to let the user provide this flag manually if she/he really
      wants to turn safety off, knows what she/he is doing, and accepts the
      risk associated with this
- the avrdude flag -D is dropped
    - This disables issuing an erase command during flashing, however this
      erase cycle is strictly required to be able to program the flash
    - This is only needed in case of the stk500v2 bootloader, which implicitly
      does the erase cycle and fails if explicitly asked to do so
    - Only for the stk500v2 bootloader this flag is now added
