Update collect-debug-logs script to include userland architecture (#1611)

Related https://github.com/tiny-pilot/tinypilot-pro/issues/1030.

Raspberry Pi OS now updates the kernel on 32-bit installations to the
64-bit kernel while simultaneously keeping the userland as 32-bit, which
means that it isn't possible to accurately determine if the user is
running a 64-bit system based on the output of `uname --all`.

This change adds additional information to the `collect-debug-logs`
script, allowing us to detect when a user is running TinyPilot on an
unsupported architecture. It also slightly reformats the relevant
section for readability.
