build: switch to autoreconf -W no-error + add macOS homebrew link dirs

Two CI fixes for v5.9.25-fork-detection run #471:

1. Windows Qt + daemon: build-libtor.sh ran ./autogen.sh which calls
   autoreconf with -W all,error. autoconf 2.73 (in MSYS2) added a new
   warning when AC_CHECK_FUNCS/AC_CHECK_HEADERS is called without a
   literal argument; under -W all,error this becomes a hard failure.
   Linux runners don't hit this because Ubuntu 22.04 ships autoconf 2.71.
   Fix: call 'autoreconf -i -f -W no-error' directly, skipping autogen.sh.

2. macOS Qt: -levent / -lssl / -lssl / -lz failed to resolve because
   Homebrew's /opt/homebrew/opt/{libevent,openssl@3,zlib}/lib paths
   aren't on the default linker search path. Configure step passes the
   include/lib paths to CMake but target_link_libraries uses bare -l,
   so the linker needs an explicit -L. Add target_link_directories
   under APPLE to inject the Homebrew lib dirs.

Both uncommitted worktree changes were in flight; this commit lands them.
