Apply Q-quoting pattern to qemu_invocation array in run_host_x86_binary_logged

[coderabbitai]

Context

In PR #9466, a review comment identified that the qemu_invocation array in run_host_x86_binary_logged should use the ${array[*]Q} quoting pattern when passed to run_host_command_logged.

Reference: #9466 (comment)

What Needs to Change

In lib/functions/logging/runners.sh around lines 207-218, the current code:

run_host_command_logged env -u QEMU_CPU "${qemu_invocation[@]}"

Should be updated to:

local -a invocation=("env" "-u" "QEMU_CPU" "${qemu_invocation[@]}")
run_host_command_logged "${invocation[*]Q}"

Why This Change is Needed

The run_host_command_logged function executes commands via bash -c "$*". When an array is expanded using "${array[@]}" and then joined by $*, any element containing spaces or shell metacharacters will be re-parsed by bash, causing:

• Incorrect word splitting
• Unintended interpretation of special characters (semicolons, pipes, etc.)

The Q parameter expansion operator shell-quotes each array element, preserving spaces and special characters when the array is joined into a string and passed to bash.

Established Pattern

This follows an established pattern in the Armbian build system. As documented in previous PRs (e.g., #9159), when calling run_host_command_logged with arrays containing arguments that might have shell metacharacters, use "${array[*]Q}" instead of "${array[@]}".

Scope

This is a robustness improvement separate from the main purpose of PR #9466 (adding 32-bit x86 support). It should be implemented in a follow-up PR to keep changes focused.
