Fix brace expansion in AIC8800 bluetooth service check across board configs

[coderabbitai]

Problem

The post_family_tweaks__enable_aic8800_bluetooth_service() function in several board configuration files uses brace expansion with test -f, which causes the test command to fail because it receives multiple arguments instead of one.

Affected Files

• config/boards/kickpik2b.csc
• config/boards/radxa-cubie-a5e.csc
• config/boards/radxa-zero3.csc

Current Problematic Code

if chroot_sdcard test -f {/lib/,/usr/lib/,/etc/}systemd/system/aic-bluetooth.service; then

Solution

Replace with explicit OR checks:

if chroot_sdcard test -f /lib/systemd/system/aic-bluetooth.service || \
   chroot_sdcard test -f /usr/lib/systemd/system/aic-bluetooth.service || \
   chroot_sdcard test -f /etc/systemd/system/aic-bluetooth.service; then

Context

This issue was identified during review of PR #8511 but deferred to a separate PR to keep changes focused.

Did you actually check the code? Because what you claim is untrue. What remained to be done, though, was to test for three file locations instead of the current two.
