main/postmarketos-ui-plasma-bigscreen: disable (MR 4883)

All of Plasma Bigscreen was removed from aports[1]. It will return with
KDE 6.1, according to PureTryOut. But for now, disable this package by
making it build on no architectures so that CI works again.

[ci:skip-vercheck]: Version does not need to change when changin arches.
