Makefile: don't look for golint and godep in specific places
Makefile: don't look for golint and godep in specific places

Using $GOPATH/bin/godep or $GOPATH/bin/golint is problematic because
$GOPATH can contain multiple colon-separated paths.

We should just run these like normal binaries. The user should make sure
their $PATH contains $GOPATH/bin, if necessary. This is part of normal
Go setup.
