kpatch-build: retrieve source package instead of linux-source

Browse Source 
On Ubuntu Trusty, HWE kernels don't come with a linux-source
package. Use dget to retrieve the source package instead. This is not
the case anymore with Xenial as the linux-source package is also
provided for the HWE kernels. For Debian, backports always come with the
linux-source package.
