perf top: Fix window dimensions change handling
The stdio perf top crashes when we change the terminal
window size. The reason is that we assumed we get the
perf_top pointer as a signal handler argument which is
not the case.
Changing the SIGWINCH handler logic to change global
resize variable, which is checked in the main thread
loop.
