perf symbols: Look for vmlinux in more places
Now that we can check the buildid to see if it really matches,
this can be done safely:
vmlinux
/boot/vmlinux
/boot/vmlinux-<uts.release>
/lib/modules/<uts.release>/build/vmlinux
/usr/lib/debug/lib/modules/%s/vmlinux
More can be added - if you know about distros that put the
vmlinux somewhere else please let us know.
