examples: hide error for missing pkg-config path flag

Some versions of pkg-config don't support the --path flag, which is not a fatal error when building the apps. Without the flag, the makefile just cannot track the .pc file of DPDK as a dependency of the build. Therefore, we can ignore the error and suppress it by redirecting to /dev/null the stderr from that call to pkg-config.
