Re: [PATCH 1/4] kunit: Drop redundant text from suite init failure message

If a suite initialization fails, then our diagnostic message will include redundant indent and hash sign as all this was already added by the kunit_printk() used by kunit_err() macro.

This could be easily seen if we force some error in our example test by modyfing example_test_init_suite() and running:

$ ./tools/testing/kunit/kunit.py run --raw_output \ --kunitconfig ./lib/kunit/.kunitconfig "example.*"

KTAP version 1
1..1
    # example: initializing suite
    # example:     # failed to initialize (-19)
not ok 1 example

Fix that and while around improve error code reporting by using error pointer format %pe that gives more user friendly output:

KTAP version 1
1..1
    # example: initializing suite
    # example: failed to initialize (-ENODEV)
not ok 1 example
