This is a preparation for cross-platform vdso lookup. There is a naming confusion about vdso name, vdso buildid generated by a 32-bit machine stores it with the name 'vdso', but when processing buildid on a 64-bit machine with the same 'perf.data', perf will search for vdso named as 'vdso32' and get failed. This patch uses different names when storing the buildid, i.e. vdso64 for 64-bit machine and vdso32 for 32-bit machine, and eliminates this naming confusion.
