cobbler-ubuntu-import: fix bug that cleaned http_proxy
from the environment if no --proxy was given
It doesn't seem to make a lot of sense, but the "" are
necessary around a '[ -n "$empty_var" ]':
$ bash -c 'x=""; [ -n $x ] && echo yes || echo no'
yes
$ bash -c 'x=""; [ -n "$x" ] && echo yes || echo no'
no
