selftests/landlock: Fix net_test build with old libc
One issue comes up while building selftest/landlock/net_test on my side
(gcc 7.3/glibc-2.28/kernel-4.19).
net_test.c: In function ‘set_service’:
net_test.c:91:45: warning: implicit declaration of function ‘gettid’; [-Wimplicit-function-declaration]
"_selftests-landlock-net-tid%d-index%d", gettid(),
^~~~~~
getgid
net_test.c:(.text+0x4e0): undefined reference to `gettid'
