eina: add test cases for eina_xattr functions.

Summary:
Add eina_test_xattr.c file for testing eina xattr functions and added test
cases for eina_xattr_set and eina_xattr_fd_set functions. Those tests need
a directory where the underlying file system allow xattr. Usually /tmp is
running on tmpfs that doesn't support today xattr. This test won't be run
if we are not provided with an existing proper directory.
