dpdkbuild: completely rebuild dpdk on SPDK config change

Browse Source 
Configuring SPDK with different options might result
in enabling different CONFIG_RTE_LIB* options, but since
it does not modify any DPDK config files, DPDK doesn't
get rebuilt and keeps using older, potentially outdated
build options.

We'll now clear dpdk/build whenever SPDK config is modified,
which will result in automatically re-configuring DPDK.
