[libFuzzer] Enable fuzz targets to build in Chromium

Browse Source 
Enable building elf_image_reader_fuzzer in Chromium.
Rename it to crashpad_elf_image_reader_fuzzer so that its clearer
where the fuzzer comes from.
Import chromium's fuzzer_test definition when building in Chromium and
make sure fuzzer is only built on Linux since it breaks fuzzer build
on Win (and maybe Mac?).
