nss: create checksum files for the nss libraries

Add checksum files required for the NSS softoken to operate in FIPS 140 mode.
The shlibsign is invoked to sign the libraries, and it is built for the target
architecture and doesn't support cross-compiling so far.

Invoke shlibsign at target's first boot time to generate checksum files.
