tools/power/x86/intel-speed-select: Use pkg-config for libnl-3.0 detection
Replace hardcoded libnl3 include path with pkg-config detection to
improve portability across different distributions and build environments.
The previous implementation used a fixed path constructed from the
compiler's sysroot, which could fail on systems with non-standard
library installations. Now the build system:
- Attempts to detect libnl-3.0 include paths using pkg-config
- Falls back to /usr/include/libnl3 if pkg-config is unavailable
- Maintains backward compatibility with existing build configurations
This ensures the tool builds correctly on a wider range of systems
while preserving existing behavior when pkg-config is not present.
Closes:https://bugzilla.kernel.org/show_bug.cgi?id=220819
