Introduce falloc_caps() to create descriptors with capabilties in place.
falloc_noinstall() followed by finstall() allows you to create and
install file descriptors with custom capabilities. Add falloc_caps()
that can do both of these actions in one go.
This will be used by CloudABI to create pipes with custom capabilities.
