Binstall support is broken

[djmattyg007]

I can see that binstall support was implemented for #860, but it's not working for me at the moment:

❯ cargo binstall mq-run@0.5.24
 INFO resolve: Resolving package: 'mq-run@=0.5.24'
 WARN resolve: Error while downloading and extracting from fetcher github.com: bin-dir configuration provided generates duplicate source path: /home/djmattyg007/.cargo/cargo-binstallWtwu2N/bin-mq-run-x86_64-unknown-linux-gnu-GhCrateMeta

 WARN The package mq-run v0.5.24 will be installed from source (with cargo)
Do you wish to continue? [yes]/no

I've got the very latest version of binstall installed at the time of writing (v1.17.9). I'm running it on Bazzite (Fedora 43).
