Add terminal icon: prompt chevron + cursor on a squircle screen panel

The Terminal desktop entry declares Icon=cce-terminal but no glyph
existed, leaving a blank slot in the launcher gutter. New svg/terminal.svg
follows the family language (f1fa8c fill, squircle r=4.5 corners as in
folder.svg, dark 0.35-opacity crease marks as in mail.svg), named for the
app via the hicolor symlink.
