YiFei Zhu 3ce4b78f73 selftests/seccomp: Fix compile warning when CC=clang
clang has -Wconstant-conversion by default, and the constant 0xAAAAAAAAA
(9 As) being converted to an int, which is generally 32 bits, results
in the compile warning:

  clang -Wl,-no-as-needed -Wall -isystem ../../../../usr/include/  -lpthread  seccomp_bpf.c -lcap -o seccomp_bpf
  seccomp_bpf.c:812:67: warning: implicit conversion from 'long' to 'int' changes value from 45812984490 to -1431655766 [-Wconstant-conversion]
          int kill = kill_how == KILL_PROCESS ? SECCOMP_RET_KILL_PROCESS : 0xAAAAAAAAA;
              ~~~~                                                         ^~~~~~~~~~~
  1 warning generated.

-1431655766 is the expected truncation, 0xAAAAAAAA (8 As), so use
this directly in the code to avoid the warning.
