tests: fix pidfd-test compilation
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. Fixes: 575a0ae9744d ("selftests: add tests for pidfd_send_signal()") Signed-off-by: Christian Brauner <christian@brauner.io>
