Provide the CloudABI vDSO to its executables.
CloudABI executables already provide support for passing in vDSOs. This functionality is used by the emulator for OS X to inject system call handlers. On FreeBSD, we could use it to optimize calls to gettimeofday(), etc. Though I don't have any plans to optimize any system calls right now, let's go ahead and already pass in a vDSO. This will allow us to simplify the executables, as the traditional "syscall" shims can be removed entirely. It also means that we gain more flexibility with regards to adding and removing system calls. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D7438
