Similar to make legal-info, produce a csv delimited file containing
all selected packages CPE identification.

Have the pkg infra define CPE_ID_* defaults using the package name
for the vendor and name as most CPE IDs seem to align with that
assumption. Also use the pkg version as the CPE ID's version field.

Changes
v2
[Thomas P
 - Moved comment on conditionals back to this patchset where
   the conditional is created vs later

v3
[Thomas P
 - Merged infra define CPE_ID_*  into this patch
 - Report all packages vs restricting to just allowing based on if
   the VENDOR was set (v2). This now represents Thomas P's original
   idea to report everything.  At first I felt I should restrict
   the reporting to those CPE IDs we had made sure were correct.
   Turns out we should have actually let the script handle fixing
   the CPEs and just make a complete design of this up front.

[Matt
 - Moved to using the _project on all vendors instead of just name
