main/postmarketos-bootsplash: revert to killing plymouth using an openrc service

plymouth-openrc-plugin (and any other OpenRC plugins really) trigger a
bug in OpenRC that only happens on musl-based systems, which can result
in a hang if a service fails.

A PR has been submitted to OpenRC to fix this bug. While the PR is
waiting for review and merging, work around this by reverting to killing
the splash from an OpenRC service to at least no longer trigger this
bug. See pmaports#4536 for more context.
