[PRQ#57980] Deletion Request for meson-rust

MarsSeed [1] filed a deletion request for meson-rust [2]: This modded variant of Arch repo's rust continues to be broken in build or in testing. The experimental patch used here is abandoned since Nov 2023. [a] Does not seem useful to keep on AUR, if it never works.
