RFR: 8274388: ProblemList gtest dll_address_to_function_and_library_name on macosx-x64

[Daniel D.Daugherty]

A trivial fix to ProblemList ProblemList gtest dll_address_to_function_and_library_name on macosx-x64.

Tested locally on my MBP13. Here's the baseline results for running the
dll_address_to_function_and_library_name sub-test:

$ grep -c dll_address_to_function_and_library_name *.baseline.jtr
GTestWrapper.fastdebug.baseline.jtr:2
GTestWrapper.release.baseline.jtr:2
GTestWrapper.slowdebug.baseline.jtr:2
NMTGtests_nmt-detail.fastdebug.baseline.jtr:2
NMTGtests_nmt-detail.slowdebug.baseline.jtr:2
NMTGtests_nmt-summary.fastdebug.baseline.jtr:0
NMTGtests_nmt-summary.slowdebug.baseline.jtr:0

Here's the results for running the dll_address_to_function_and_library_name sub-test
with the fix in place:

$ grep -c dll_address_to_function_and_library_name *.8274388.jtr
GTestWrapper.fastdebug.8274388.jtr:0
GTestWrapper.release.8274388.jtr:0
GTestWrapper.slowdebug.8274388.jtr:0
