proc/native: better error message when building on unsupported systems (#1883) 
As we rearrange the code and the Go compiler changes the error message
returned by the compiler on unsupported architectures will change too,
making it un-googlable. Since the error message tends to be rather
obscure too this regularly confuses newbies.

This is an effort to make the error message for unsupported GOOS/GOARCH
combinations the same across all unsupported combinations and to make
it more user friendly.

Directories containing Go source code are supposed to contain a single
package. This property happens to be checked by cmd/go itself so it
will happen even before the syntax is fully checked and therefore has a
high probability of being the first (and only) error message being
print.

Here we take advantage of this by adding to the pkg/proc/native
directory a file with a bad package line that only gets compiled in on
unsupported GOOS/GOARCH combinations.

At present the error message for compiling Delve on unsupported systems
will be:

service/debugger/debugger.go:21:2: found packages native (proc.go) and your_operating_system_and_architecture_combination_is_not_supported_by_delve (support_sentinel.go) in $PATH_TO_DELVE/pkg/proc/native

About Delve

Delve is a debugger for the Go programming language. The goal of the project is to provide a simple, full featured debugging tool for Go. Delve should be easy to invoke and easy to use. Chances are if you're using a debugger, things aren't going your way. With that in mind, Delve should stay out of your way as much as possible.
