build: Add goreleaser

Automates binary builds for multiple platforms. More info on this tool
is at https://goreleaser.com.

There is also a Github action for GoReleaser. I might add it later.

The config file may also set env vars, but it doesn't meet my needs for
setting up LDFLAGS, so I'm keeping that in the Makefile. For
consistency's sake, the other env vars are also in the Makefile.

+# env vars are put together with the Makefile.

+# For each build item (https://goreleaser.com/customization/builds/), it'd be
+# nice if we could set the common values for "ldflags" somewhere, such as this
+# env section, and then tack on any driver-specific values, such as
+# .versionDriver, for each driver. As of goreleaser v2.0.1, it does not look
+# possible to access common Name Template values (https://goreleaser.com/customization/templates)
+# from this env section. An alternative approach would be to set the ldflags
+# value for each build item, which can access both Name Template, and
+# Environment variable values. Example:
+#
+# ldflags:
+# ->
+# -X {{ .ModulePath }}/internal/cmd.versionBranchName={{ .Branch }}
+# -X {{ .ModulePath }}/internal/cmd.versionBuildTime={{ .CommitDate }}
+# -X {{ .ModulePath }}/internal/cmd.versionCommitHash={{ .ShortCommit }}
+# -X {{ .ModulePath }}/internal/cmd.versionGoVersion={{ .Env.GOVERSION }}
+# -X {{ .ModulePath }}/internal/cmd.versionTag={{ .Tag }}
+# -X {{ .ModulePath }}/internal/cmd.versionDriver=name_of_driver_here
+#
+# But I'd prefer to not repeat that same structure for each driver to build at
+# this time.
