[Buildroot] [git commit] support/scripts/pkg-stats: add CPE searching links

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=c5aa3c5883aec704050c15c97adde920e58856bb
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For cases of a CPE having a unknown version or when there hasn't
been a CPE verified, proposed a search criteria to help the
user research an update.

(libcurl has NIST dict entries but not this version)
  cpe:2.3:a:haxx:libcurl:7.76.1:*:*:*:*:*:*:*
  CPE identifier unknown in CPE database (Search)

(jitterentropy-library package doesn't have any NIST dict entries)
  no verified CPE identifier (Search)
