xuname ARM fixes

Turns detected CPU in output from Unknown to Qualcomm on my OnePlus 5 :)

Void 5.17.0-rc4 aarch64-musl Qualcomm uptodate rFF

This may need some more work for 32-bit ARM as reportedly RPi shows ARM instead of Broadcom (is there a proper way to even detect this correctly?)

I mean 32 vs 64bit we see in the architecture already, so not sure if this is such a great improvement.

I just thought it would be nice to see the CPU vendor in the output like we do on x86 systems (GenuineIntel / AuthenticAMD) especially when consider there's a lot more vendors on non-x86 arches

Would trying awk '/^Hardware/{print $NF;exit}' /proc/cpuinfo before env LC_ALL=C lscpu | sed -n 's/^Vendor ID:[[:space:]]*//p' for the CPU detection be fine? If there's spaces on the Hardware field this would ofc only grab the last part and I'm not sure if that could be problematic.

On RPi 4 for example it should result in BCM2835, so your xuname output would look something like:

Void 5.15.61_1 aarch64-musl BCM2835 uptodate rFFF

This also works on apple silicon, produces Apple instead of Unknown.
