perf branch: Add system error and not in transaction branch types

This updates the perf tool with generic branch type classification with
two new branch types i.e system error (PERF_BR_SERROR) and not in
transaction (PERF_BR_NO_TX) which got updated earlier in the kernel.

This also updates corresponding branch type strings in
branch_type_name().

Committer notes:

At perf tools merge time this is only on PeterZ's tree, at:

  git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git perf/core

So for testing one has to build a kernel with that branch, then test
the tooling side from:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/core
