[WIP] Add libnss build and 15 fuzzers from crrev.com/1677803002. (#12)

* Add libnss build and 15 fuzzers from crrev.com/1677803002. * Added missing $LDFLAGS and used /out/*.a. * Another attempt to link statically. The best one so far. * Manually linking with nspr/Linux*/pr/src/misc/prlog2.o. * Cleanup nss/buil.sh script and disable 2 of 15 nss fuzzers for now. * Fix comments.
