dpdk: fix finding librt

Browse Source 
The generated pkg-config libdpdk.pc file has the output
with full path of librt such as
<builddir>/recipe-sysroot/usr/lib/librt.so
instead of -lrt.

This will cause an issue when compile DPDK app
with static library as the librt is not found with the
hardcode path in the libdpdk.pc file.

Subject: [PATCH] ifpga/meson: Fix finding librt using find_library()
Finding with "librt" keyword would give the output
with full path of librt such as /usr/lib/librt.so
instead of -lrt.
Assume find_library() will prepend "lib", thus remove
"lib" from "librt" keyword. The output will shows as
-lrt.
