ci: remove material-unit-tests failure blocklist (angular#32138)

Initially when the `material-unit-tests` job got wired up,
Ivy was not really backwards-compatible and a few bugs caused
test failures when running the Angular Material test suites w/ Ivy.

These bugs got fixed progressively and eventually the test
blocklist became empty. At this point we don't want to regress
in the future and the blocklist should never have new items.

Additionally since we switched the unit-tests job to run against
Angular Material `master` with Bazel, the blocklist is no
longer respected. Therefore we can safely remove the blocklist.
