unbreak debugallocation_test on Solaris

Allow debugallocation death test to accept RUN_ALL_TESTS in backtrace
instead of main. For some reason solaris ends up either optimizing
tail-calling of RUN_ALL_TESTS or something else happens in gtest
platform integration, but failure backtraces don't have main
there. But the intention of the test is simply to ensure that we got
failure with backtrace. So lets accept RUN_ALL_TESTS as well.
