Close file descriptors of ProfilerInfo

When using "am start --start-profiler" command, am doesn't close
instances of related ParcelFileDescriptor of the profiler file path,
but relies on garbage collection, so at the system level the file
kept open for longer than it is needed. In a result, some processes
that monitors the file close event using unix inotify_add_watch
method would wait 20~30 Seconds.

This change closes file descriptors after passing it to ActivityThread
process, which is similar to what "am profile start" does.
