JDK-8010734 - NPG: The test MemoryTest.java needs to be updated to support metaspace

JDK-8019500 - Exclude MemoryTest.java and MemoryTestAllGC.sh to enable integration
Description
The test java/lang/management/MemoryMXBean/MemoryTestAllGC.sh does not take the Metaspace MemoryMXBean into account when counting the number of non-heap memory pools.

An example of a failure:

Exception in thread "main" java.lang.RuntimeException: TEST FAILED:             
Number of non-heap pools = 2 but expected <= 1 and >= 1                         
    at MemoryTest.checkMemoryPools(MemoryTest.java:113)                         
    at MemoryTest.main(MemoryTest.java:75)
Comments
The test MemoryTestAllGC.sh is just a shell wrapper around MemoryTest.java, the fix for MemoryTest.java will fix MemoryTestAllGC.sh as well.
