Skip o3 qpy full path transpile test on windows

In CI we're seeing a reliable failure on windows when scipy is calling
LAPACK. This appears to be unrelated to the change in this PR branch and
is isolated to specific windows environments. This commit adds a skip
condition to skip that one test to workaround the failure in CI. The
wider issue with scipy compatibility on windows is being tracked in
issue Qiskit#10345, when we have a conclusion to that and can reliably run
this test we should remove this skip condition.
