[Buildroot] [PATCH] acpid: Make bundled event files optional

[Alexander Sverdlin <alexander.sverdlin@gmail.com>]

On one hand the preinstalled /etc/acpi/events/powerbtn is not part of
acpid, one other hand others might want to implement more complicated logic
on power button. Therefore, make it optional.
