package/linux-pam: drop useless LINUX_PAM_CPE_ID_NAME definition
This definition is useless, because it is equal to the default value
of <pkg>_CPE_ID_NAME as calculated by generic-package.
Before and after this patch, the CPE ID calculated for the linux-pam
package is exactly the same, according to "make linux-pam-show-info".
