LU-5680 tests: Remove use of /etc/motd from sanity-hsm

In sanity-hsm tests, /etc/motd is copied to the file system
and archived. /etc/motd may not exist in some Linux distributions
and, if exists, may be of size 0 and may defeat the use of
bandwidth control for timing. Uses of /etc/motd are replaced
with a generated file of known suitable size.
