cpt: remove cpt-stat and cpt-readlink, add _stat() and _readlinkf

cpt-readlink and cpt-stat were unnecessary additions for mundane tasks. Since
they were binaries instead of scripts, they added an extra layer of complexity
to the library.

These functions are now included inside the package manager library with the names
_readlinkf() and _stat().
