Title: build: allow to specify custom tags

When building custom `node` versions (e.g., floating features/fixes from
different versions) it's often useful to specify a custom tag which
easily identifies build when invoking `node -v`.

Introduce a way to specify this tag in `node_version.h` file. Insert it
right after the patch version (and before `-pre`, if build is not a
release).
