dpdk: fix compiling issue with clang
When building vpp image with below command, clang reports warnings/errors
on the unused option '-L', as it's not linking stage, and does not require
linking libraries.
In dpdk.mk, the linking library path should be attached to
DPDK_EXTRA_LDFLAGS, instead of DPDK_EXTRA_CFLAGS
$ make build-release CC=clang V=1
