Fixup severe build performance issues

Make variable substitution calling bumpversion and other commands
introduce by osmo-release.mk has severely slowed down builds.

Inside the makefile we could use $(eval FOO:=$(shell...)) constructs
to have variable substitution only happen once the 'release' target
is executed. However, 'ifeq' and friends don't work with such late
constructs. Let's shift all release action into a helper shell script
that is called from the Makefile instead.

This way we get the best of both worlds: No performance impact during
normal builds, and the convenience of 'make release'.
