include/pidfd-utils: remove hardcoded syscall fallback

Based on https://github.com/util-linux/util-linux/pull/3018

The syscall numbers should not be hardcoded in the header file. If we
really need them, there is UL_CHECK_SYSCALL() to define the numbers
for different architectures. I doubt it's really necessary. Just
update your kernel header files to get the latest kernel updates ...
