turn off build of ecore-txt and ecore-config by default.

turn off build of ecore-txt and ecore-config by default.

These are deprecated and will be killed in short time, stop using them!

Recommendations:

 * ecore-txt: use eina_str_convert, drop in replacement, just sed.

 * ecore-config: convert your code to use eet + Eet_Data_Descriptors
   directly, it is simpler and faster, but requires you to change your
   code. Consider using eet_data_descriptor_file_new() and
   eet_eina_file_data_descriptor_class_set() or
   EET_EINA_FILE_DATA_DESCRIPTOR_CLASS_SET(). Then describe your type
   with EET_DATA_DESCRIPTOR_ADD_*().
