nss: fix non-determinism when create a blank certificate

It uses certutil from nss to create a blank certificate. But the
checksum of database file key4.db changes every time:

$ certutil -N -d sql:. --empty-password
$ md5sum *
f9dac2cfcb07cc8ca6db442a9a570906  cert9.db
b892c5ff7c1977d4728240b0cf628377  key4.db
7b9136cb03f07ae62eb213a5239fda71  pkcs11.txt
$ rm *

$ certutil -N -d sql:. --empty-password
$ md5sum *
f9dac2cfcb07cc8ca6db442a9a570906  cert9.db
405d55178e866a115c1aa975fccfa764  key4.db
7b9136cb03f07ae62eb213a5239fda71  pkcs11.txt

Provide pre-created databases with a blank certificate to fix
non-determinism issue. And these database files are from nss qemux86-64
build.
