media-libs/tg_owt: Bump to 0_pre20210626

Adds desktop capture and makes a return of several use flags including
alsa and pulseaudio, patched around to make sure they work.

Added a subslot, since the ABI of this package has broken, and requires
the rebuild of media-libs/libtgvoip before net-im/telegram-desktop can
be built...

+Add -DTG_OWT_USE_X11
+
+Allows disabling X11 desktop capturing independently of pipewire support, for
+the few people that run wayland without any X11 support whatsoever.
+
+This setup is untested, but supported by the GNI build system, see:
+* src/modules/desktop_capture/BUILD.gn (option rtc_use_x11_extensions)
+
+Toggling the WEBRTC_USE_X11 define also affects some files under
+src/modules/audio_device, but that falls under "X11 support", regardless...
