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'.
