scripts/populate: add option to use an alternate sysroot

Add a new command line option, "-r", which allows the user to specify
an alternate sysroot location to copy libraries from.  This is useful
when using the toolchain in combination with a separate root filesystem,
or when working with multiple different root filesystems.
