perf archive: Don't try to collect files without a build-id
To avoid these error:
[root@doppio ~]# perf archive
tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat:
No such file or directory
tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat:
No such file or directory
tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat:

tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat:
No such file or directory
tar: Exiting with failure status due to previous errors
[root@doppio ~]#
More work is needed to support archiving symtabs for binaries
without a build-id, perhaps creating a perf.data UUID + adding
build-ids for the binaries copied into the cache and then have
this perf.data session UUID be a directory with symlinks to the
by now calculated build-id of the files inside it.
Or just do an extra pass and insert the calculated build-ids in
the perf.data header.
