Use "." to refer to the current path's package in reflect mode

[XSAM]

Introduction

I use go:generate in my source code to invoke mockgen to generate mocked interfaces.

e.g.

//go:generate mockgen -destination=mocks/foo.pb.go github.com/xxx/xxx/pkg/xxx Foo

But it's too annoying that every time I have to write and check the package name (github.com/xxx/xxx/pkg/xxx).

And add the full package name in a source file is kind of duplicated information since golang could parse the file path and get the package name.

Feature request

So I want to add a feature that can use . to refer to the current path's package.

e.g.

//go:generate mockgen -destination=mocks/foo.pb.go . Foo

Just a single ., no more github.com/xxx/xxx/pkg/xxx.

This seems like a reasonable and useful feature, I'm +1 for adding this.

@nguyenfilip @codyoss WDYT?

@cvgw Yeah seams reasonable
