Add systemtap package

Add systemtap, one of the tracing/profiling tools mentioned in the Yocto v1.0 tracing/profiling tools list posted here:

https://lists.yoctoproject.org/pipermail/yocto/2010-November/000281.html

This patch adds the recipe for systemtap support for the architectures that I was able to get working and test - basically x86, x86-64, qemux86, and qemuppc (arm (tried qemuarm) apparently needs some work upstream, and mips isn't supported).

There is an accompanying kernel config patch that's also needed for systemtap to work.

In addition to the systemtap recipe and kernel options posted here, there's also a small amount of setup needed on the host system in order to run systemtap scripts on a target system - basically, installing systemtap on the host. I also hacked up a shell script ('crosstap') to make it easier to compile and execute systemtap scripts on a target system - if you want to use that, you should replace the variables in that script with appropriate values for your system (I actually started out having the build system generate the script, but decided to do that later if it ended up being desirable).

Detailed instructions on the setup as well as the 'crosstap' script can be found in a new section on the wiki I've added for tracing and profiling to the Yocto wiki:
