8283562: JDK-8282306 breaks gtests on zero

[satyenme]

Backporting JDK-8283562: JDK-8282306 breaks gtests on zero. Fixes test by skipping on platforms where we expect/know os::current_frame() will be zero (such as armv7). Trivial backport, only touches test code and adds additional disabling condition.

/approval request for backport of "8283562: JDK-8282306 breaks gtests on zero". JDK-8282306 introduced os.is_first_C_frame_vm, but that breaks on zero since the test relies on os::current_frame(), which on all zero platforms is almost empty. This change skips the test on those platforms.

Testing: tier 1 and 2 tests and gtest suite.

Risk: low/almost none. Only touches test code, adding an exclude condition for the is_first_C_frame test. Essentially a trivial fix.

Could you please explain why you would be skipping the test on all JDK zero builds? Does this test fail for example on Linux amd64 zero?
