CMakePM: Copy auto package-manager to ${buildDir}/.qtc/ directory

By copying the ${IDE:ResourcePath}/package-manager to
${buildDir}/.qtc/ the problem with hardcoding paths
to old an Qt Creator version can no longer occur.

This also fixes the issue with remote projects by reffering
to the code residing on the host.

With the above issues fixed, enable "Package manager auto setup"
by default.
