tui/suspend_event(): set STDIN to "blocking"

Browse Source 
Set STDIN to blocking on "suspend". This was missed in #2598.
See 8a782f1699.

Also on "continue"/SIGCONT explicitly set STDIN back to NON-blocking.
We don't explicitly do that on *startup* (libuv does it internally),
but on "continue" it seems wise to restore libuv's expectations.

Closes #5459
