perf(scripts): replace /dev/random with /dev/urandom for swap keyfile generation

Browse Source 
This change improves performance and reliability during installation by
preventing potential hangs caused by the blocking nature of /dev/random.
/dev/urandom is non-blocking and provides sufficient cryptographic
entropy for generating swap keyfiles in modern Linux environments.
