PCI: endpoint: pci-epf-test: Select configfs

Like some of the other endpoint modules, pci-epf-test now also uses
configfs, but is missing an indication in Kconfig:

  arm-linux-gnueabi-ld: drivers/pci/endpoint/functions/pci-epf-test.o: in function `pci_epf_test_add_cfs':
  pci-epf-test.c:(.text.pci_epf_test_add_cfs+0x2c): undefined reference to `config_group_init_type_name'

Select the symbol as needed.
