plugins/sudoers/ldap_util.c cuts off last char of role cn

[johnzozo]

The calculated size doesn't account for the space between sudoRole and the CN which results in the last character of the LDAP role cn being cutoff by snprintf.

sudo/plugins/sudoers/ldap_util.c

Lines 481 to 484 in 4fef09e

	size_t slen = sizeof("sudoRole") + strlen(priv->ldap_role);
	if ((source = sudo_rcstr_alloc(slen)) == NULL)
	goto oom;
	(void)snprintf(source, slen, "sudoRole %s", priv->ldap_role);

A correction could look something like:
size_t slen = sizeof("sudoRole ") + strlen(priv->ldap_role);
