Subject: [PATCH v2 07/45] powerpc/ptdump: Limit size of flags text to 1/2
 chars on PPC32

In order to have all flags fit on a 80 chars wide screen,
reduce the flags to 1 char (2 where ambiguous).

No cache is 'i'
User is 'ur' (Supervisor would be sr)
Shared (for 8xx) becomes 'sh' (it was 'user' when not shared but
that was ambiguous because that's not entirely right)
