perf symbols: Add the build id cache to the vmlinux path
So that if the kernel DSO has a build id because record inserted it in
the perf.data build id table in the header, or a BUILD_ID event was
inserted in the stream, we first look at the build id cache
($HOME/.debug/).
If we find it there, try to use it, allowing offline annotation in
addition to 'perf report'.
