Jonathan Anderson af098ed8e7 Add kernel functions to unwrap capabilities. 
cap_funwrap() and cap_funwrap_mmap() unwrap capabilities, exposing the
underlying object. Attempting to unwrap a capability with an inadequate
rights mask (e.g. calling cap_funwrap(fp, CAP_WRITE | CAP_MMAP, &result)
on a capability whose rights mask is CAP_READ | CAP_MMAP) will result in
ENOTCAPABLE.

Unwrapping a non-capability is effectively a no-op.

These functions will be used by Capsicum-aware versions of _fget(), etc.
