Previously, the keyname and key fields of the Ecore_Event_Key
structure were being filled in with the capitalized version of the
key. This is due to xkb_keysym_get_name always returning keys with the
modifier applied. There is no actual function in xkbcommon to Not do
this :/ so we have to manually check if Shift is pressed, and if so
then we need to convert the key to lowercase.
Fixes T550
