[PATCH v2] tests/functional: Remove sleep workarounds from sh4 test

["Cédric Le Goater" <clg@redhat.com>]

These were introduced in the avocado tests to workaround read issues
when interacting with console. They are no longer necessary and we can
use the expected login string instead.

Test always passes now. Remove skipUnless test on QEMU_TEST_FLAKY_TESTS.
