This fixes some skas mode-related bugs, including
generalizing some code which made assumptions that UML always has
a tracing thread
moving a header out of arch/um/kernel/skas/include because it's not
private to skas mode
adding the ability to skas mode of detecting some signals from the
host and shutting down as a result
process name modification doesn't happen if CONFIG_MODE_TT isn't enabled the 'mode=tt' switch generates warnings if the configuration makes it
either redundant or useless
