package/net-tools: fix static linking issue with lintl

When net-tools are build with uClibc-ng and statically linked,
some tools like hostname and route needs to link with -lintl.

Adding -lintl in LDFLAGS place the library before object files:
arm-linux-gcc -O2 -g -Wall -fno-strict-aliasing   -static -lintl -Llib -o hostname hostname.o

Add $(LIBS) after object files in the Makefile to place -lintl correctly.

Rework NET_TOOLS_BUILD_CMDS to set LDFLAGS with only TARGET_LDFLAGS and
set LIBS with -lintl when needed.
