Subject: [PATCH] Include fuzzers to build by default

Compilation errors in fuzzers are often overlooked when building locally
adding fuzzers (when configured) to build automatically helps to detect errors earlier.

list of all fuzzers was generated with a command
gn ls out/Default "//test/fuzzers:*" | grep "fuzzer$" | sed 's/\/\/test\/fuzzers\(.*\)/"\1",/'
