Schutzfile: pin osbuild 50

CentOS Stream 8 is lagging behind, so let's pin osbuild v50,
under the assumption that things land in CS8 in the same order
they landed in RHEL8, so we don't run the risk of an old osbuild
with a new composer.

Fedora 35 is also stuck on an old osbuild, we will have to take
care to release osbuild 50 into F35 before the next composer.

Usually we would not want to pin like this, but we would
otherwise block the next composer release in RHEL.
