redhat: Fix the condition for pyverbs enablement on Fedora 32 and up

The cited commit enabled pyverbs build by default for Fedora 32 and up.
However, it broke enalbing pyverbs build when passing '--with pyverbs' flag.

Fix the condition so that now the behavior for Fedora 32 and up will be:
 * Default: pyverbs enabled.
 * --with pyverbs: pyverbs enabled.
 * --without pyverbs: pyverbs disabled.

Fixes: 07b304b ("redhat: Build pyverbs for Fedora greater than release 31")
