[Buildroot] [git commit branch/2019.08.x] package/go: security bump to version 1.12.12

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a3882d58aa393cff7224ca02f994ebfbc89d19b7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.08.x

Fixes the following security issues (1.12.11):

- CVE-2019-17596: Invalid DSA public keys can cause a panic in dsa.Verify.
  In particular, using crypto/x509.Verify on a crafted X.509 certificate
  chain can lead to a panic, even if the certificates don’t chain to a
  trusted root.  The chain can be delivered via a crypto/tls connection to a
  client, or to a server that accepts and verifies client certificates.
  net/http clients can be made to crash by an HTTPS server, while net/http
  servers that accept client certificates will recover the panic and are
  naffected.

Additionally, 1.12.11 fixes a number of issues. From the release notes:

fixes to the go command, runtime, syscall and net packages.
