Fix Failed to load translation for English (#3351) 
Upon the first start of cppcheck-gui, the following message appears,
if the language of the OS is English:
  Failed to load the user interface language:
  Failed to load translation for language English from file
  cppcheck_en.qm
  The user interface language has been reset to English.

- Update translationhandler.cpp and check if the language code starts
  with "en". The code can be e.g. "en_US"
