adb: Don't clobber block devices during push
In the past, an adb push would ALWAYS unlink the target path.
Now, we only links and regular files (and links).
This allows the following to work:
adb shell ls -l /dev/block/mmcblk0p8
# brw------- root root 179, 8 2013-11-28 07:43 mmcblk0p8
adb push n7.jpa.mda.post_jb_encryption.raw /dev/block/mmcblk0p8
