rpm: ensure rpm2cpio call rpm relocation code

We need to call rpmcliInit to ensure the rpm relocation code is called.
when we allow rpm2cpio to be relocatable, The adjusted path used to find
the macro files was being built into the binary and this path was valid
for the machine it was built on and some of our other build machines,
but invalid on some others, and was not being properly overridden at
runtime.

when we export the wrsdk and source the sdk, then execute rpm2cpio xxx.rpm|cpio -t.
we will get the following error :
"rpm-5.4.14/rpmdb/dbconfig.c:493:
db3New: Assertion `dbOpts != ((void *)0) && *dbOpts != '\0'' failed.
