Use sequence number to check if to reload atrace tags.

This is to deprecate the sysprop change notification in atrace.
After this change, processes will only update their enabled tags
at the first atrace event. Previously we reloaded the tags as a
result of the sysprop changed Binder notification, which woke up
every process in the system.

Test: adb shell su root atrace -t 10 ss
Test: #define ATRACE_SHMEM 0; adb shell su root atrace -t 10 ss
