qmi: increase SIM power-cycle timeouts

Some modems and SIM cards take a bit longer to initialize after UIM has been
powered off. Waiting too little time can cause the qmi protocol to end up
in a loop repeatedly power-cycling the SIM card.

Avoid that by
 a) increasing the time we unconditionally sleep after --uim-power-on
 b) increasing the time we allow uqmi to wait for response for --uim-get-sim-state
