wolf: fix ti99sim-sdl build — it needs real SDL 1.2, not SDL2

Browse Source 
Confirmed live: the previous sdl-config shim got past the tooling
problem, but hit a much deeper one — ti99sim's SDL frontend
(src/sdl/main.cpp) is written against the actual SDL 1.2 API and uses
symbols SDL2 genuinely removed (SDL_keysym, SDL_WM_SetCaption,
SDL_EnableUNICODE, SDL_JoystickOpened, the old integer-index
SDL_JoystickName). No shim can paper over missing symbols — this needed
the real thing.

Swapped libsdl2-dev + the hand-rolled sdl-config shim for
libsdl1.2-compat-dev — the SDL project's own official compatibility
package (libsdl-org/sdl12-compat, packaged in Ubuntu's universe repo):
genuine SDL 1.2 headers and its own real sdl-config, implemented on top
of actual SDL2 underneath. The code compiles against the API it was
actually written for, while still running on modern SDL2 at runtime.

# ti99sim's own Makefile.linux calls the old SDL 1.x `sdl-config`
# tool, which no longer exists — modern libsdl2-dev ships only
# pkg-config .pc files (and sometimes sdl2-config, itself already
# a thin wrapper over pkg-config). Confirmed live: without this,
# every sdl-config call silently returns nothing, so the compile
# gets no -I/-L flags at all and fails on "SDL.h: No such file or
# directory" — not a real incompatibility, just a stale tool
# name. A tiny shim mapping the handful of flags this build
# actually uses (--cflags/--libs/--version) onto pkg-config sdl2
# fixes it without patching the project's own Makefiles.
