Patch fixing the bug

Arch Linux builds glibc in a systemd-nspawn. To avoid issues with the
testsuite, we disable some tests that require syscalls not allowed by nspaw=
n.
Commit (bisected) 325ba824b0611e14e96b38dbc486acf255f9e568 introduced a han=
g of
make after printing the test summary at the end.

The root cause in sysdeps/unix/sysv/linux/tst-pidfd.c is the early return in
line 150 which is causing the process, spawned in line 46, to hang on line =
84
waiting for the signal in line 170.

Patch attached.
