Update timeout logic for connectivity reports.

Typically, BUGREPORT_MODE_TELEPHONY takes single-digit seconds, which
leaves the routine waiting for just USER_CONSENT_TIMEOUT_MS (30 seconds)
for the user to respond. Given the sizeable dialog with lots to read, we
don't believe this is a reasonable default.

We increase the timeout specifically for MODE_TELEPHONY to be 2 minutes,
which should then roughly match the time it takes a full report to be
generated, and plenty of time for the user to fully read the consent
dialog.

Bug: 146521742
Test: manual, ensure timeout happens after 2 minutes instead of 30
seconds
