[SSSD] [PATCH] sysdb: try dealing with binary-content attributes

I have here a LDAP user entry which has this attribute
loginAllowedTimeMap::
AAAAAAAAAP///38AAP///38AAP///38AAP///38AAP///38AAAAAAAAA
In the function sysdb_attrs_add_string(), called from
sdap_attrs_add_ldap_attr(), strlen() is used to populate the .v_length
member of a struct ldb_val - and this will set it to zero.
Subsequently, this makes ldb_modify(), called from
sysdb_set_entry_attr(), return LDB_ERR_INVALID_ATTRIBUTE_SYNTAX.
