Add support for 32bit operating systems on 64bit arm hardware

[legolasbo]

Thanks a lot for providing this ansible role. It worked great for my 32 bit raspberrypi 3b running 32 bit linux and my 64 bit Odroid running 64 bit linux.

Unfortunately it didn't result in a working golang installation on my 64 bit Raspberry Pi 4b's running 32 bit linux. The operating system would keep reporting "No such file or directory" when I tried to execute the binary. It turned out that the ansible role only looks at the hardware architecture when choosing which binary to install.

This PR changes that behaviour slightly to also look at the userspace_bits fact, which will have the value 32 on 32bit OS's and 64 on 64bit OS's.

I've tested the changed role on all my SBC's and it works like a charm.
