Header check ignore --kernelsourcedir

Bug #1838045 reported by Stefan Bader on 2019-07-26

	Xenial	Fix Released	Medium	Stefan Bader

Bug Description

In Ubuntu 16.04/Xenial the dkms command (2.2.0.3-2ubuntu11.7) ignores the provided kernel source directory and then fails by not finding the headers.

This was fixed upstream in 2.2.0.3-5 and landed in 18.04/Bionic. Proposing to backport the additional line of code into Xenial.

+ [ ! -z "$ksourcedir_fromcli" ] && DIR=$kernel_source_dir

Testcase:
Trying to compile any DKMS module with kernel source (headers) in a non-standard location (/usr/src) will fail with an error reporting missing headers without the change, even using --kernelsourcedir. With the patch applied, this works.
