GCC doesn't like dereferencing a pointer set to 0x1 (when building
at -O2):
pkey_sighandler_tests.c:166:9: warning: array subscript 0 is outside array bounds of 'int[0]' [-Warray-bounds=]
166 | *(int *) (0x1) = 1;
| ^~~~~~~~~~~~~~
cc1: note: source object is likely at address zero
Using NULL instead seems to make it happy. This should make no difference
in practice (SIGSEGV with SEGV_MAPERR will be the outcome regardless), we
just need to update the expected si_addr.
