0161a94e2d tools: gpio: Correctly add make dependencies for gpio_utils
gpio tools fail to build correctly with make parallelization:

$ make -s -j24
ld: gpio-utils.o: file not recognized: file truncated
make[1]: *** [/home/labbott/linux_upstream/tools/build/Makefile.build:145: lsgpio-in.o] Error 1
make: *** [Makefile:43: lsgpio-in.o] Error 2
make: *** Waiting for unfinished jobs....

This is because gpio-utils.o is used across multiple targets.
Fix this by making gpio-utios.o a proper dependency.

8674cea84d tools/gpio: move to tools buildsystem
There is a nice buildsystem dedicated for userspace tools in Linux kernel tree.
Switch gpio target to be built by it.
