Fix: Optimized "gvmd --get-users" and "gvmd --get-roles" command.

Optimized the "gvmd --get-users" and the "gvmd --get-roles"
command by skipping the update of the nvti cache in those
cases.
Also added a retry loop around "lockfile_lock_nb (...)" so that
commands like "gvmd --get-users" don't fail if another gvmd
process is starting up.
