ioquake3 does not install on aarch64

[dszakallas]

ioquake3 does not install on raspberry pi 4b+ (aarch64):

Could not successfully build ioquake3 - Quake 3 source port (/home/luigi/RetroPie-Setup/tmp/build/ioquake3/build/release-linux-aarch64/ioquake3.aarch64 not found).

the problem is that the build script translates aarch64 to arm64

https://github.com/ioquake/ioq3/blob/main/Makefile#L13-L15

so the target detection at https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/ports/ioquake3.sh#L35 is incorrect.

This quick and dirty change resolves the issue
