Use sysdb_attrs_get_string_array() instead of sysdb_attrs_get_el()

sysdb_attrs_get_el() creates an empty element in the sysdb_attrs
structure if the requested element does not exist. Recent versions of
libldb do not accept empty elements when writing new objects to disk.
sysdb_attrs_get_string_array() does not create an empty element but
returns ENOENT.
