`aftman self-install` fails when /tmp is on a seperate filesystem

[Joshument]

When installing aftman on a unix-like operating system, aftman self-install will fail if /tmp is on a seperate filesystem (i.e. tmpfs)

[INFO  aftman::tool_storage] Updating all Aftman binaries...
Aftman error: failed to rename file from /home/josh/.aftman/bin/rojo to /tmp/.tmpaVMK5X/rojo

Caused by:
    Invalid cross-device link (os error 18)
