Daniel Bertalan 1f747b9132 CMake: Use CMAKE_POSITION_INDEPENDENT_CODE instead of explicit -fpic
This makes CMake pass `-fpie` instead of `-fpic` to the compiler when
building the Kernel and userland *executables*. This allows the compiler
to make certain optimizations based on the fact that the code will be
used in an executable, such as not having to emit `.localalias` symbols.
This leads to a 450 KiB decrease in the size of the Kernel binary.
