perf symbols: Ditch vdso global variable
We can check using strcmp, most DSOs don't start with '[' so the test is cheap enough and we had to test it there anyway since when reading perf.data files we weren't calling the routine that created this global variable and thus weren't setting it as "loaded", which was causing a bogus: Failed to open [vdso], continuing without symbols Message as the first line of 'perf report'.
