Invert wrong boolean condition in filesystem test

the conditionals have been introduced in
8960a51
which states (emphasys mine):

> The new partition rules are **in** osbuild-composer v94 and higher.

but the condition was "not v94 or higher" and as a result it fails on
8.10 nightly with osbuild-composer v92 with:

failed to initialize osbuild manifest: The following custom mountpoints are not supported [\"/boot/firmware\" \"/foobar\"]
