[PATCH] util-linux: Disable flaky script/options-size test

[PATCH] util-linux: Disable flaky script/options-size test

[Paul Barker]

The test case for the --output-limit / -o option to `script` is flaky
due to the way the output limit is handled. Depending on how buffer
boundaries line up, the command may output different numbers of
characters, but the test case expects the output to always be identical.

This has been raised upstream [1], as there are multiple options for
fixing this - we can change the behaviour of script, or we can relax the
test case. Changing the behaviour of script may impact users so we don't
want to rush ahead and do that.

For now, we're going to disable the test case.
