[Powertop] [PATCH] csstoh shell-script for cross-compiling PowerTOP

It was impossible to build PowerTOP for ARM with a cross-compiler
because PowerTOP uses internal csstoh utility that converts
powertop.css to powertoh.h for inclusion in *.cpp source files.

When you use the cross-compiler (without making complicated rules
in the Makefile) this utility will be compiled for ARM platform too.
And you cannot run it on x86 build host.

To solve this issue I have rewritten it in a shell script.
