activate-linux: 1.1.0 -> 1.2.0

Upstream 1.2.0 switched text rendering to pangocairo for font
fallbacks, so add pango to buildInputs.

Also adapt the install phase to upstream asset changes: res/icon.png
was renamed to res/activate-linux.png, and the desktop file now ships
Icon=activate-linux, making the substituteInPlace patch obsolete.

Add meta.changelog.
