audit: move audit_aux_data_execve contents into audit_context union
audit_bprm() was being called to add an AUDIT_EXECVE record to the audit context every time search_binary_handler() was recursively called. Only one reference is necessary, so just update it. Move the the contents of audit_aux_data_execve into the union in audit_context, removing dependence on a kmalloc along the way.
