lantiq: do not "local" variables outside of a function

Older busybox versions allowed using the local keyword outside of
functions, whereas 1.25.0 (which was introduced in 06fa1c46fc) do not
allow this anymore (leading to the following error when executing the
script: "file: local: line nn: not in a function").
