packages: add sysprof tool

Add sysprof - preformance profiler
for Linux - to the development tools.

Patches for mips/arm are from openembedded
code.

sysprof-cli <outfile> get required events/stack frames.
Next outfile can be loaded/displayed on PC using
sysprof.

Tool using:
- PERF events
- /proc/kallsyms for kernel symbols

You should compile kernel with profiling enabled,
debug information, symbol table information.
