Evas textblock: Fix crash with empty markups values
Markup parsing will segv if a value string is empty, as in "<style=>". Sure, this is invalid, but hey, it could definitely be used from an app or even by a user writing his own markups :) The internal doc says this function expects an item to be of the form "key=val" but there are no checks beyond the presence of "=" in the string before calling it.
