build: use package name instead of abs path for golint in the Makefile
build: use package name instead of abs path for golint in the Makefile

Now that golint does not require an absolute path anymore, it's much
easier to just use the package name.

A "go get -u" for golint has also been added in the "make dev-deps"
rule, because "..." and relative path are only supported in recent
version of golint.
