mapi: Workaround a bug in makedepend.

makedepend would crash when a source includes a header indirectly, such
as

  #define HEADER "some-header.h"
  #include HEADER

Do not define HEADER (makedepend would detects this as an incomplete
include) and add the dependency manually in the Makefile.

This should hopefully fix bug #33374.
