'command -x': also bypass path-bound built-ins (re: 66e1d446)

Browse source 
Since 'command -x' provides xargs-like functionality to repeatedly
run external commands if the argument list is too long for one
invocation, it makes little sense to use with built-ins. So I
decided that 'command -x' should double as a way to guarantee
running an external command. However, it was only bypassing plain
built-ins and not path-bound builtins (the ones that show up with a
virtual directory path name in the output of 'builtin').

src/cmd/ksh93/sh/path.c:
- Before looking for a path-bound built-in, check that the SH_XARG
  state bit is not on. This needs to be done in path_absolute() as
  well as in path_spawn().
