cmd/dist: make registerTest take a goTest
The overall goal is to make registerTest the primary entry point for
adding dist tests and to convert nearly all dist tests to be
represented by a goTest, registered via registerTest. This will
centralize the logic for creating dist tests corresponding to go tool
tests.
I traced all exec calls from cmd/dist on linux/amd64 and this makes
only no-op changes (such as re-arranging the order of flags).
For #37486.
