cmd/go: restore TestLegacyMod as a script test

This test was apparently mistakenly removed without a replacement in
CL 213223, but its testdata was left in the tree. This change removes
the orphaned testdata subdirectory, and restores the test that
previously used that data as a self-contained script.

For #27494.
