RFR(xs): 8225219: [TESTBUG] AppCDS tests timed out with -Xcomp and --limit-modules option won't work with Graal

[Calvin Cheung]

bug: https://bugs.openjdk.java.net/browse/JDK-8225219

webrev: http://cr.openjdk.java.net/~ccheung/8225219/webrev.00/

This change includes:

1. increase the timeout value so that the tests won't timeout with the 
-Xcomp option;

2. exclude the test scenarios which use the --limit-modules option from 
running if Graal is enabled.

Tested locally on linux-x64 and passed tier1/2.

thanks,

Calvin
