depends: Boost 1.74.0

- The old patch is no longer necessary because of this upstream fix:
    https://github.com/boostorg/build/pull/560

- Boost 1.72 removed a <deque> from an include, which exposed a missing
  include in src/httpserver.cpp.

- Boost 1.73 moved function placeholders into the boost::placeholders
  namespace.

- The new patch is a fix from just after Boost 1.74 was released, fixing
  a warning that was missed.
