Subject: [PATCH] Fix SDL check_header_includes=1 build

Type `SyncGLMethod` was defined conditional on DXX_USE_OGL, but header
`common/include/ogl_sync.h` used `SyncGLMethod` unconditionally.  This
works fine in the normal build since SDL builds never include
`common/include/ogl_sync.h`, but broke the check_header_includes=1 test
since that compiles `common/include/ogl_sync.h` even for SDL builds.

Wrap type `ogl_sync` in `#if DXX_USE_OGL` to hide it from the
check_header_includes=1 test in SDL mode.
