Disable strip related tests on Android

[oech3]

Android does not have strip. Thus, those tests always fails.

[github-actions]

GNU testsuite comparison:

GNU test failed: tests/date/date-locale-hour. tests/date/date-locale-hour is passing on 'main'. Maybe you have to rebase?
GNU test failed: tests/date/resolution. tests/date/resolution is passing on 'main'. Maybe you have to rebase?
Congrats! The gnu test tests/tail/tail-n0f is now passing!
