selftests/resctrl: Simplify cleanup in ctrl-c handler

Ctrl-c handler isn't aware of what test is currently running. Because of
that it executes all cleanups even if they aren't necessary. Since the
ctrl-c handler uses the sa_sigaction system no parameters can be passed
to it as function arguments.

Add a global variable to make ctrl-c handler aware of the currently run
test and only execute the correct cleanup callback.
