samples: pidfd: fix userprogs typo

The Makefile adds pidfd-metadata to "usertprogs-always-y", which kbuild
does not know, so the sample has not been built since the conversion to
userprogs, even with CONFIG_SAMPLE_PIDFD=y.

Fix the variable name. pidfd-metadata.c builds without warnings with
gcc and clang for x86_64 and arm64.
