[RFC 08/15] kselftest: Do not use shell environment

[Anton Mikanovich <amikan@ilbers.de>]

To make package build process independent of the shell environment we
should remove KSELFTEST_ARGS passing through export call. The same
logic can be done by internal recipe parser and then pass variable to
template-based debian/rules file.
