RFR(XS): 8139900: [TESTBUG] Remove G1UpdateBufferSize and InitialBootClassLoaderMetaspaceSize from TestOptionsWithRanges

[Dmitry Dmitriev]

Hello,

Please review fix for TestOptionsWithRanges.java test. In this fix I 
remove two flags("G1UpdateBufferSize", 
"InitialBootClassLoaderMetaspaceSize") from testing because their 
maximum value would consume too much memory and take a lot of time. Also 
I increase timeout value for the test, since number of flags with ranges 
were increased recently.

Testing: ran on all platforms including arm's(test for few arm's are 
still in progress).

Thanks,
Dmitry
