src/Makefile LIBS path assignment under Debian 9 and Fedora 30

[adam-burns]

When running make in the top directory in Fedora 30

make

Unlike Debian 9, the compile environment under Fedora 30 is not forgiving enough to allow the top Makefile to build source with

sources:
        THREADS=${THREADS} make -C src

with src/Makefile LIBS defined with path prefix beginning with src/ as well.

Removal of src/ $LIB path prefix still allows sucessful compilation under Debian 9(!) but also stops Fedora 30 from burping with

gcc -Wall -fPIE -fPIC -pie -O3 -I. -Iredis/deps/hiredis -Iredis/deps/jemalloc -o modprobe modprobe.o kmod_log.o -L src/redis/deps/hiredis -l:libhiredis.a -Llibdowse -l:libdowse.a -lkmod
/usr/bin/ld: cannot find -l:libhiredis.a
collect2: error: ld returned 1 exit status

This patch allows compilation under both OS environments:
