Looks like the dependencies on seatd-dev and wroomd-dev have been added
by mistake, these packages do not exist. Instead move seatd-openrc and
wroomd-openrc to the openrc subpackage.
Fixes: 7a5970f6 (" main/postmarketos-ui-bananui: add -openrc subpackage (MR 5374)")
This allows the audio switching backend stuff to work on all UIs (see
!5072 / 87d355e08). For example, users of any UI can switch audio
backends by installing one of the pmos-base-ui-audio-* metapackages.
