tests: skip restart_syscall.test on x32

The syscall number of restart_syscall returned by the kernel in case
of ERESTART_RESTARTBLOCK is broken on x32 from the beginning, see
https://lkml.org/lkml/2015/11/30/790

Until that improves, skip the test on x32.

* tests/restart_syscall.c (main) [__x86_64__ && __ILP32__]: Return 77.
