perf symbols: Try to load vmlinux from buildid database
Currently we don't check on kernel's vmlinux the same way as we do for normal binaries, but we either look for kallsyms file in build id database or check on known vmlinux locations (plus some other optional paths). This patch adds the check for standard build id binary location, so we are ready once we start to store it there from debuginfod in following changes.
