Subject: [PATCH] radtest: use $HOSTNAME for the NAS name when it is set

radtest derives the NAS name from `hostname` or `uname -n`, neither of
which is guaranteed to be present in a minimal image. Prefer the
$HOSTNAME environment variable when the shell exports it, and keep the
original command substitution as the fallback.
