build: swap pci with bus_pci libs on the list

bus_pci depends on pci so it shall be listed before, otherwise it can
result in linking issue e.g.

/usr/bin/ld: /home/jkalwas/spdk/dpdk/build/lib/librte_bus_pci.a(bus_pci_pci_common.c.o): in function `pci_parse':
pci_common.c:(.text+0x6e): undefined reference to `rte_pci_addr_parse'
