use sudo only when necessary #8

try sudo only when it seems necessary. i.e. when we actually got EACCES.

motivations:

the use of sudo involves some side effects which might be undesirable. for example, as sudo is a setuid binary, LD_PRELOAD is unset. it makes difficult to use this with a rump kernel. http://netbsd.gw.com/cgi-bin/man-cgi?rumphijack++NetBSD-current
as priv/procket command can be used to open arbitrary /dev files, it's better to just allow a user to open eg. /dev/bpf instead of allowing him sudo procket.
