[dpdk-stable] [PATCH v2] ifpga/base/meson: fix looking for librt

[mohamad.noor.alim.hussin@intel.com]

From: Mohamad Noor Alim Hussin <mohamad.noor.alim.hussin@intel.com>

Finding with "librt" keyword would give the output with full path of librt such
as /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/librt.so
instead of -lrt in libdpdk.pc pkg-config file.

Assume find_library() will prepend "lib", thus remove "lib" from "librt"
keyword. The output will shows as -lrt.

This will cause an issue when compile DPDK app with static library as the
path of librt has been hard-coded in the libdpdk.pc file.
