Capture and expose build-time meta data
Summary:
The `go build` tool can accept linker options that dynamically set
variable values at build time. Let's make use of that in our `Makefile`
and `debian/rules` to know and expose meta data such as version and Git
commit at runtime.
Test Plan:
Run `make bin/blubber && bin/blubber --version` and verify that it outputs
"0.0.1-[git head commit]". Build and install the debian package and verify
the same using the installed binary.
