This reverts commit 7caa0bd1acc6fe9727bb3a91851560d756c40ab8.

* target -> subsystem in instrumentatio macro

target is not correct either, and the correct way of using a top level
target = LOG_TARGET does not work, as the macro expects a string literal
and gets confused by the constant `LOG_TARGET`.

* Use kebab-case for spa names.
