Zhao Zhili 864d4bf2da avfilter/vf_drawtext: fix newline rendered as .notdef glyph
GET_UTF8 advances the pointer past the newline byte before the
newline check, so shape_text_hb receives text that includes the
newline character. Since HarfBuzz does not treat U+000A as
default-ignorable, it gets shaped into a .notdef glyph.

Fixes #21565
