[PATCH 1/4] depmodwrapper-cross: Take into consideration kernel package name

[Andrei Gherzan <andrei@gherzan.com>]

From: Andrei Gherzan <andrei.gherzan@huawei.com>

depmodwrapper assumes that the kernel package name is "kernel". Since
this is configurable via KERNEL_PACKAGE_NAME variable, the wrapper can
easily look in the wrong place. This change adds an optional positional
argument that can be used to provide the kernel package name - when not
provided, it defaults to "kernel" (current behaviour).
