[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.
