all: explicitly list pseudo syscall dependencies
Pseudo syscalls can (and most of the time) do invoke normal system
calls. However, when there's a risk that those calls might not be
present, syzkaller needs to take preventive actions - prepend the
corresponding defines. Otherwise syz-executor or C reproducers might
not compile on the host machine.
List those dependencies in sys/targets, check them during machine check
and add the corresponding defines during C source generation.
