userspace: remove vestigial '?' cases from top-level getopt(3) loops

getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument.  We can
handle this case with the "default" failure case with no loss of
legibility.  Hence, remove all the redundant "case '?':" lines.

Prompted by dlg@.  With help from dlg@ and millert@.

look(1): use a stricter pledge(2) in lieu of unveil(2)

We're only reading one file here, so unveil(2) is overkill.  We can
achieve the same effect with just pledge(2):

- Start with an initial pledge(2) of "stdio rpath" at the top of main().
  We know we need to read a file at this point but don't yet know which
  one.

- Drop the pledge(2) down to "stdio" after we open(2) and fstat(2) the
  chosen file.

- Dropping "rpath" obviates unveil(2).

For open/openat, if the flags parameter does not contain O_CREAT, the
3rd (variadic) mode_t parameter is irrelevant.  Many developers in the past
have passed mode_t (0, 044, 0644, or such), which might lead future people
to copy this broken idiom, and perhaps even believe this parameter has some
meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from
mode_t on a number of system calls as a safety factor, and his bewilderment
that this appeared to be happening against valid modes (at least visually),
but no sorry, they are all irrelevant junk.  They could all be 0xdeafbeef.

When system calls indicate an error they return -1, not some arbitrary
value < 0.  errno is only updated in this case.  Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

look(1) will access /usr/share/dict/words to look for the string we want, or it
may access another file instead if we mention it via argument. In order to know
which file to unveil(2) we need to push down pledge(2) a little bit after
getopt(3) and now that we know the name of the file we can unveil(2) it only
with read permissions.
