Modify to create .pc file with BuildRequire packages

If some other package BuildRequires this hal-rootstrap package with
pkgconfig, it refers hal-rootstrap.pc for the locations of includes and
libraries.
Thus, to make them buildable, it is required to include all possible
paths of headers and libraries in the .pc file.
The script modify_pc.py reads every .pc files then modifies
hal-rootstrap.pc file to include them.
