backends/native: explicitly pause on suspend

Browse Source 
The kernel forces a VT switch during suspend on some hardware,
and not on others.

We run code from the VT switch handler that we need to also get
run on resume.

This commit makes sure we explicitly run the VT switch handler
during suspend and resume.
