Subject: [PATCH] gnu: celestia: Update to 1.6.4-0.d3f4040.

This is a follow-up to 51640e48200a0b8c5234be62683e89439de1be64.

Celestia is built from the latest commit providing Qt6 support and many
other new features.

* gnu/packages/astronomy.scm (celestia): Update to 1.6.4-0.d3f4040.
[buld-system]: Switch to cmake-build-system.
[arguments] <configure-flags>: Adjust it for the build.
<phases>: Remove 'patch-lua-version; add 'install-content.
[inputs]: Remove freeglut and libtheora; add eigen, ffmpeg, fmt,
freetype, gperf, libavif, libepoxy, qtbase, and qtwayland.
[propagated-inputs]: Add perl.
[native-inputs]: Remove autoconf, automake, libgit2, libtool, and perl;
add boost and celestia-content.
