Revert "Evas textblock: Properly ifdef hyphenation out." 

This reverts commit 5b083ace84.

The "--enable-hyphen" option refers to using the optional hyphenation
dictionaries. We support hyphenation via SHY-HYPHEN hints regardless of
this option.
The following commit will provide finer handling to address the issue in
the reverted one.
