perf archive: Add helper script to package files needed to do analysis
It uses 'perf buildid-list --with-hits' to create a tarball with
what is needed to have in the destination machine ~/.debug
hierarchy to properly decode the perf.data file specified.
Here is an example where a perf.data file collected on a x86-64
machine running Fedora 12 is used and then the data is packaged,
transferred and decoded on a PARISC64 machine running Debian
Testing, 32-bit userspace:

Probably the next step is to have 'perf report' notice that there is a
perf.data.tar.bz2 file in the same directory and look if it was already
added to ~/.debug/.
