Adjust setComponentEnabled broadcast delay. 

The original broadcast delay for package changed has been reduced to one
second from ten seconds to avoid a delayed reaction from the receiver.
If package manager service was started within the past minute, the default
delay of ten seconds will remain to avoid thrashing on boot.

Bug: 79778864
Test: manual (observe DW "show icon" setting before and after one minute)
