scripts/rpm2cpio.sh: Use 'xz -dc' instead of xzcat

rpm2cpio.sh calls xzcat to decompress,and xzcat is equivalent to:
xz --decompress --stdout (-d and -c, in short)

Since commit d1930f8, it is assumed that xz is provided, but 'xzcat'
used in rpm2cpio.sh is not listed in HOSTTOOLS. With it being only a
symlink, and with commit eb3ec74 replacing bzip2 with bunzip2 in a
similar way, this fixes the bin_package class for rpm without adding
xzcat to HOSTTOOLS.
