Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

Do not return success when checking for execute permission by super-user and no
execute bits are set. Also, this test is no longer needed in execve(2).

Use sigcode fields in package structure. This seems to be the cleanest
way to deal with seperate trampoline code for emulation of other OSs,
it avoids having to clutter up kern_exec.c any further.
