clk: explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in .kunitconfig

CONFIG_UML_PCI_OVER_VIRTIO=y is needed to enable CONFIG_PCI=y on UML.
However, this causes test failures when running the clk tests, i.e.
$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/clk

A snippet of the particular error is:
>     ok 1 - clk_gate_test_parent_rate
> ------------[ cut here ]------------
> WARNING: CPU: 0 PID: 45 at lib/logic_iomem.c:141 __raw_readl+0x9f/0xd0

This is triggered by this cast in the test:
   143          ctx->fake_mem = (void __force __iomem *)&ctx->fake_reg;
this seems to work except when logic iomem is enabled, i.e.
CONFIG_INDIRECT_IOMEM=y.

As a short-term fix, explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in
drivers/clk/.kunitconfig so we can enable it for everyone else by
default in kunit.py.

The long-term fix probably requires something more complicated, like
  #ifdef CONFIG_INDIRECT_IOMEM
    logic_iomem_add_region(...);
  #endif
