gccspecs/hardened-cc1: also pass -fPIE to cpp by default.

Browse source 
Note that -fPIE defines __PIC__ and __PIE__, so passing this on to
pure cpp(1)/gcc -E executions is relevant.

Found the hard way due to ccache breaking on i686 with precompiled
headers which used the non-PIC definitions in cpuid.h since header
precompilation doesn't read cc1_options.
