Fold "malloc" into "stdio" and -- recognizing that no program so far has

used less than "stdio" -- include all the "self" operations.  Instead of
different defines, use regular PLEDGE_* in the "p_pledgenote" variable
(which indicates the operation subtype a system call is performing).  Many
checks before easier to understand.  p_pledgenote can often be passed
directly to ktrace, so that kdump says:
 15565 test     CALL  pledge(0xa9a3f804c51,0)
 15565 test     STRU  pledge request="stdio"
 15565 test     RET   pledge 0
 15565 test     CALL  open(0xa9a3f804c57,0x2<O_RDWR>)
 15565 test     NAMI  "/tmp/testfile"
 15565 test     PLDG  open, "wpath", errno 1 Operation not permitted
