zephyrtest.bbclass: refactor

Only keep code/variables related to individual test/package names.
Moved ZEPHYR_TEST_SRCDIR into zephyr-kernel.inc as it is
zephyr kernel version specific.
Moved ZEPHYR_MAKE_OUTPUT into zephyr-kernel-common.inc as it is
as it is not zephyr test specific but applicable to all
zephyr images.
Additional minor cleanup.
