[dpdk-stable] [PATCH v2] mk: remove library search path from binary

[Ferruh Yigit]

This patch functionally reverts the patch in fixes line to not have any
hardcoded library path in the final binary for the security reasons, in
case this binary distributed to production environment.

RPATH only added in RTE_DEVEL_BUILD case and this binary shouldn't
distributed, but still removing it to be cautious.

Fixes: 8919f73bcbaa ("mk: add build directory to library search path")
