[PATCH] sched.h: increment TASK_COMM_LEN to 20 bytes

[Luben Tuikov]

Lets use 19+1 chars.  This helps display properly
kernel threads (e.g. SATA translation threads) which bear
the address of the STP/SATA bridge where the SATA disk is
connected. Those are 16+1 chars long.  Currently (15+1) the last
character is not displayed as it is used by the '\0'.

The array is 4 byte aligned so we add another 4 bytes to it.
