fastfetch: update to 2.21.3 and fix CPU info

[GaugeAndGravity]

I copied this from https://gitlab.archlinux.org/archlinux/packaging/packages/fastfetch/-/blob/main/PKGBUILD?ref_type=heads with a little edit, and it works fine for me. Fixes #10

Only tested on my MOREFINE Loongson-3A6000-HV-7A2000-NUC...

Hello, fastfetch author there. Can you paste the content of /proc/cpuinfo for debugging?

BTW, the empty line after the first line stops parseCpuInfo(), so CPU shows as "Unknown".
