Tidies up Makefile: fixes default target, remove unused ones and makes phony targets to by be truly phony

[m1kola]

Description

• Fixes default target. It looks like target all was previously define first to implicitly set build to be default target, but since introduction include above the all target - now BINGO is default target. This change explicitly sets build to be default.
• Sets several targets as phony as they are not targeting a file and moves .PHONY closer to target definition for better visibility.
• Removes unused wait target

Reviewer Checklist

• API Go Documentation
• Tests: Unit Tests (and E2E Tests, if appropriate)

re the unused wait target - do we know if anyone was calling make wait as part of their workflow?

[m1kola]

@ncdc I believe this was introduced to be used by run target. At some point wait was removed from run as a dependency. So wait seems to be obsolete.

I think it is not documented anywhere nor it appears in make help. I think it is relatively safe to remove it.
