Add all NSS files to allow using a complete NSS in the future.

Add all NSS files to allow using a complete NSS in the future.

The new files are:
1. the built-in root CA certificates
- mozilla/security/nss/lib/ckfw/*
2. the libpkix certificate verification library
- mozilla/security/nss/lib/libpkix/*
- nss/mozilla/security/nss/lib/certhigh/{certvfypkix.c,certvfypkixprint.c}

The new files are excluded from the build by default.

To review this CL, please

1. verify that the new files are in three groups:
- mozilla/security/nss/lib/certhigh/certvfypkix*.c
- mozilla/security/nss/lib/ckfw/*
- mozilla/security/nss/lib/libpkix/*

2. review nss.gyp and scripts/nss-checkout.sh 

Thanks.
