[dev.regabi] os: disable TestDirFS until #42637 is fixed

This test is causing nearly every trybot run on dev.regabi and
dev.typeparams to fail. It's already a release blocker for Go 1.16, so
the failures on the development branches is entirely noise; and
because it causes the trybots to short-circuit, it risks masking
actual Windows-specific failures.

This CL disables the test until a proper solution is decided upon and
implemented for Go 1.16.

Updates #42637.
