[PATCH][SAUCY][GROUPER] UBUNTU: [Config] enable deadline I/O scheduler by default

From: Colin Ian King <colin.king at canonical.com>

Testing shows that the deadline scheduler on the flash file system
performs slightly better than CFQ.  It also consumes marginally less
power.  So enable deadline by default.
