scripts/tags.sh: Don't tag usages of DECLARE_BITMAP

scripts/tags.sh: Don't tag usages of DECLARE_BITMAP

For all bitmap declarations like
  DECLARE_BITMAP(x, y);
ctags generates multiple DECLARE_BITMAP tags for each usage
because it doesn't expand the DECLARE_BITMAP macro.

Configure ctags to skip generating tags for DECLARE_BITMAP in such cases.

The #define DECLARE_BITMAP itself and declared bitmaps are
tagged correctly.
