net-tools: Ensure quilt only operates on local patches

When net-tools is built and the local patches haven't been applied, then
`quilt pop -a` will climb parent directories attempting to find a
{patches/.pc} directory; if this succeeds then we end up popping off
some completely unrelated patches from a parent directory.

Ensure that we do have a local patches directory and then turn off the
directory climbing so that we avoid this problem.
