package_rpm.bbclass: Accomodate dash when using arrays

we were assigning local variable to an array coming through
positional arguments. local is a non posix contruct thats
also supported by dash luckily but operates differently in this
case it exapnds the array before assignment. so

local pkgs="$@"

turns into pkgs=locale-base-en-us locale-base-en-gb

ant we see errors

run.do_rootfs.25593: 932: local: locale-base-en-gb: bad variable name

So lets not use defining and assigning local in one go
first define a local and then the assignment
