net-im/telegram-desktop: convert webkit-gtk dependency to OPTIONS (+)

- Add WEBKIT option, disabled by default
- Bump PORTREVISION, default dependencies was changed

Previously dropped GTK option was used to enable gtk native dialogs
and render rich window content.
With last releases WebKit-gtk used only for in-app payments system.
While internal payments still experimental and not wide used,
there is no reason to hook this burden to the build as default yet.

Discussed with:	osa, danfe, maintainer via ML
Approved by:	maintainer
