RFR: 8359182: Use @requires instead of SkippedException for MaxPath.java

[SendaoYan]

Hi all,

I think use `@requires (os.family == "windows")` is more elegrant than thow jtreg.SkippedException in test java/io/File/MaxPath.java.

On linux before this PR, run this test jtreg report:


TEST: java/io/File/MaxPath.java
TEST RESULT: Passed. Skipped: jtreg.SkippedException: This test is run only on Windows


On linux after this PR, run this test jtreg report:


Test results: no tests selected


Change has been verified locally both on linux and windows, test-fix only, no risk.
