[LTP] [PATCH v2] route{4, 6}-rmmod: Declare variables before using them

[Feiyu Zhu]

When running route4-rmmod case, it reports the following error:
/opt/ltp/testcases/bin/route4-rmmod: line 100: lhost_module: unbound variable.

It fails because "set -u" is used in .testcases/lib/cmdlib.sh and
"set -u" treats unset variables and parameters as errors.
