cpio: fixes for Android kernel build.

Allow -pd to work by changing -p from an option that takes an
argument to an option that implies there will be an argument (that
is, `-pd x` is `-p -d x` with x being the directory for -p, rather
than `-p d x` with d being the directory, as we previously interpreted
it).

Fix -d (aka --make-directories) to not be a no-op. Previously we
acted as if this was always on.

Accept --quiet and effectively just ignore it, since toybox cpio
doesn't seem to produce any output that --quiet would suppress.
