tests: fix pidfd-test compilation

Browse source 
Define __NR_pidfd_send_signal if it isn't to prevent a potential
compilation error.

To make pidfd-test compile on all arches, irrespective of whether
or not syscall numbers are assigned, define the syscall number to -1.
If it isn't defined this will cause the kernel to return -ENOSYS.
