Math of -Cc is off

[RubenKelevra]

I've ran aura 4.0.8 twice with -Cc back-to-back with different parameters, with no other operations ongoing and noticed, that the math is off:

❯ aura -Cc 1
aura :: Current cache size: 16.02GB
aura :: 1 of each package file will be kept. The rest will be deleted.
aura :: Proceed? [Y/n] y
aura :: 1.14GiB freed.

❯ aura -Cc 0
aura :: Current cache size: 13.78GiB
aura :: 0 of each package file will be kept. The rest will be deleted.
aura :: Proceed? [Y/n] y
aura :: 13.78GiB freed.

Good catch, I'll double-check.
