MediaScanner: delete abnormal elements in prescan procedure.

There is a race in MediaProvider's mUnmountReciver.
when it doing external storage's database clean up at power down procedure,
if the datebase is big, system may shutdown after db.update, but db.delete
not done, there will be many elements with no filename in the database.
That may cause duplicated files and folders shown in MTP.

This patch clean up these abnormal elements in MediaScanner's prescan procedure.

Keyguard: Reduce font size of clock in status keyguard (sw720dp)

When system clock is configure for a 24H clock, times like 22:22, overflows the clock
of the keyguard status view on sw720dp. This change reduces the font size of clock to
allow to fit all time formats.
