hurd: Make _hurd_intr_rpc_mach_msg avoid returning MACH_SEND_INTERRUPTED
When the given options do not include MACH_SEND_INTERRUPT,
_hurd_intr_rpc_mach_msg (aka mach_msg) is not supposed to return
MACH_SEND_INTERRUPTED. In such a case we thus have to retry sending the
message.
This was observed to fix various occurrences of spurious
"(ipc/send) interrupted" errors when running haskell programs.
