RFR: 8266449: cleanup jtreg tags in compiler/intrinsics/sha/cli tests

[Igor Ignatyev]

Hi all,

could you please review this small cleanup of jtreg tags in compiler/intrinsics/sha/cli tests? 
- `@modules` tags are not needed since we have changed the used test libraries not to depend on `java.management` module and `jdk.internal.misc.*` classes;
- `testcases`  isn't required in `@library` b/c the files this directory contains are accessible from `/` `@library`.

Thanks,
-- Igor
