RFR: 8281822: Test failures on non-DTrace builds due to incomplete DTrace* flags handling [v2]

[Aleksey Shipilev]

> A test failure reproduces in GHA in x86_32 mode. Reproduces locally too:

> $ CONF=linux-x86-server-fastdebug make run-test TEST=serviceability/7170638/SDTProbesGNULinuxTest.java

> java.lang.Error: java.lang.RuntimeException: '.note.stapsd' missing from stdout

> The reason is that the new test now enables `DTraceMethodProbes`, `DTraceAllocProbes`, `DTraceMonitorProbes`, but VM never actually checks those options are available. So test thinks dtrace support is there, yet there are no relevant sections in `libjvm.so`, so the test fails. We should extend the argument checks to those three options too.

> Unfortunately, there are tests that do `DTrace*` flags, we should make them sense the build capability, and act accordingly. This simplifies some existing tests too.
> 
> Additional testing:
>  - [x] Linux x86_64 fastdebug (dtrace enabled), affected test still passes
>  - [x] Linux x86_32 fastdebug (dtrace disabled due to missing dependencies), affected test now passes
