Subject: [PATCH] kpatch-build: allow overriding of distro name

It is sometimes useful to have ability to override
distro name, for example during cross-compilation
build when livepatch modules will be ran on the
target which differs from host.

This patch adds a new --distro option which
implements all needed functionality
