[compiler-rt] Removed unnecessary 'REQUIRES: shell' from lit tests. (#157951)

As part of our work to migrate tests to use the lit internal shell by
default, this removes 'REQUIRES: shell' from tests that don't actually
require it. In one case the test was updated slightly to pass without
requiring shell.
