env: restore old env_get_char() behaviour

Browse Source 
With multiple environments, the 'get_char' callback for env
drivers does not really make sense any more because it is
only supported by two drivers (eeprom and nvram).

To restore single character loading for these drivers,
override 'env_get_char_spec'.
