travis: remove clang-analyze (#2917)

• The output currently contains a large number of false-positives and — AFAICT —
  no actual issues.

• Upstream shows little interest in addressing the long-standing issues with the
  TAILQ macros, so the false-positive situation probably won’t change soon:
  https://bugs.llvm.org/show_bug.cgi?id=18222

Currently, we largely spend travis CPU cycles on this, for no additional value.
