cmd/pprof,runtime/pprof: disable test on more broken platforms

Browse Source 
runtime/pprof has a more complete list of platforms with broken
profiling than I used in cmd/pprof in https://golang.org/cl/325809.
Duplicate that list in cmd/pprof and clean it up a bit in runtime/pprof
for easier reference.
