This update also fixes a memory leak that was caused by blocks not being
deallocated and just collecting every single frame, slowly accumulating
memory until OOM.
Fixes#7724
Background at the end of the commit message. The fix in libxev is
described in the PR and commit we pin to here, but basically we swap
read for poll for eventfd/timerfd.

This should make testing Flatpak builds a lot easier.
To build, enter `flatpak/` directory and run:
flatpak-builder --repo=repo builddir com.mitchellh.ghostty.yml
alternatively, using org.flatpak.Builder flatpak:
flatpak run -p org.flatpak.Builder \
--repo=repo \
builddir \
com.mitchellh.ghostty.yml
The resulting flatpak can be installed using
flatpak install ./repo com.mitchellh.ghostty
